be_cmd_read_port_transceiver_data assumes that it is given a buffer that
is at least PAGE_DATA_LEN long, or twice that if the module supports SFF
8472. However, this is not always the case.
Fix this by passing the desired offset and length to
be_cmd_read_port_transceiver_data so that we only copy the bytes once.

This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.
Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.
Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.
No functional changes.

The driver gets the pf_num for Skyhawk and Lancer using
GET_FUNC_CONFIG FW command. But since that command is not
supported in BEx, we need to get it from some other command.
Otherwise TPE recovery would fail since all NIC PFs would
end up with a func num of 0. There's a pci function number
field in the response of GET_CNTL_ATTRIBUTES command that
can be read to get the same info for BEx adapters.

This patch supports recovery from UEs caused due to Transient Parity
Errors (TPE), in BE2, BE3 and Skyhawk adapters. This change avoids
system reboot when such errors occur. The driver recovers from these
errors such that the adapter resumes full operational status as prior
to the UE.
Following is the list of changes in the driver to support this:
o The driver registers its UE recoverable capability with ARM FW at init
time. This also allows the driver to know if the feature is supported in
the FW.
o As the UE recovery requires precise time bound processing, the driver
creates its own error recovery work queue with a single worker thread (per
module, shared across functions).
o Each function runs an error detection task at an interval of 1 second as
required by the FW. The error detection logic already exists for BEx/SH,
but it now runs in the context of a separate worker thread.
o When an error is detected by the task, if it is recoverable, the PF0
driver instance initiates a soft reset, while other PF driver instances
wait for the reset to complete and the chip to become ready. Once
the chip is ready, all driver instances including PF0, resume to
reinitialize the respective functions.
o The PF0 driver checks for some recovery criteria, to determine if the
recovery can be initiated. If the criteria is not met, the PF0 driver does
not initiate a soft reset, it retains the existing behavior to stop
further processing and requires a reboot to get the chip to operational
state again.
o To allow each function to share the workq, while also making progress in
its recovery process, a per-function recovery state machine is used.
The per-function tasks avoid blocking operations like msleep() while in
this state machine (until reinit state) and instead reschedule for the
required delay.
o With these changes, the existing error recovery code for Lancer also
runs in the context of the new worker thread.

The ndo_set_rx_mode() and ndo_add/del_vxlan_port() calls may be called with
BHs disabled. The driver currently issues the required cmds to the FW in
these contexts and polls on completions from the FW, while BHs remain
disabled. This can cause either packet loss or packet reception to be
delayed on that CPU.
This patch defers processing of the above cmds to a separate workqueue.
With this change, FW cmds are now issued only in process context.
Now that the FW cmds are issued only in process context, they can sleep
waiting for a completion instead of polling. All the spin_lock_bh(mcc_lock)
calls are now replaced with mutex calls.
Also a new rx_filter_lock is now needed to protect the RX filtering fields
like vids[] between be_vlan_add/rem_vid() and __be_set_rx_mode() contexts.

On SR-IOV profiles, when the user connects a Linux Bridge or OVS to a BE3
vport, they suffer the "broadcast/multicast echo" problem. BE3 EVB echoes
broadcast and multicast packets back to PF's vport confusing the
Linux bridge. BE3 relies on the src-mac addr being programmed on the
interface to avoid sending back an echo of a broadcast or multicast packet
on a vPort. When a Linux bridge is connected to a BE3, the mac-addr of the
VM behind the bridge doesn't get configured on the vPort and so echo
cancellation doesn't work.
This patch worksaround this problem by disabling the EVB initially
and re-enabling it *only* when SR-IOV is enabled by the user. For the
driver fix to work, the BE3 FW version must be >= 11.1.84.0.

Currently, we do not distribute queue resources to enable RSS for VFs
in multi-channel/partition configurations.
Fix this by having each PF(SRIOV capable) calculate it's share of the
15 RSS Policy Tables available per port before provisioning resources for
all the VFs.
This proportional share calculation is done based on division of the
PF's MAX VFs with the Total MAX VFs on that port. It also needs to
learn about the no: of NIC PFs on the port and subtract that from
the 15 RSS Policy Tables on the port.

Skyhawk does support wake-up from ACPI shutdown state - S5, provided the
platform supports it (like Auxiliary power source etc). The changes listed
below are done to fix this.
1) There's no need to defer the HW configuration of WOL to be_suspend().
Remove this in be_suspend() and move it to be_set_wol() ethtool function
so it is configured directly in the context of ethtool. This automatically
takes care of the shutdown case.
2) The driver incorrectly uses WOL_CAP field in the FW response to
get_acpi_wol_cap() command, to determine if WOL is enabled. Instead the
driver must rely on the macaddr field in the response to infer WOL state.
3) In be_get_config() during init, if we find that WOL is enabled in FW,
call pci_enable_wake() to enable pmcsr.pme_en bit. This is needed to
support persistent WOL configuration provided by the FW in some platforms.
4) Remove code in be_set_wol() that writes to PCICFG_PM_CONTROL_OFFSET
to set pme_en bit; pci_enable_wake() sets that.

When the PF driver provisions resources for VFs, it currently only looks
at max RSS queues available to calculate the number of VF queue pairs.
This logic breaks when there are less number of TX-queues than RSS-queues.
This patch fixes this problem by using the max-TXQs available in the
PF-pool in the calculations. As a part of this change the
be_calculate_vf_qs() routine is renamed as be_calculate_vf_res() and the
code that calculates limits on other related resources is moved here to
contain all resource calculation code inside one routine.

And currently some of the frequently used fields in the driver like
the producer and consumer indices of the queues are declared as u16.
This patch declares such fields as u32. With this change we see the
64-byte packets per second numbers improve by about 4%.

This patch adds support for ethtool's --get-dump option in be2net,
to retrieve FW dump. In the past when this option was not yet available,
this feature was supported via the --register-dump option as a workaround.
This patch removes support for FW-dump via --register-dump option as it is
now available via --get-dump option. Even though the
"ethtool --register-dump" cmd which used to work earlier, will now fail
with ENOTSUPP error, we feel it is not an issue as this is used only
for diagnostics purpose.

Commit 72ef3a88fa8e ("be2net: set pci_func_num while issuing
GET_PROFILE_CONFIG cmd") passed a specific pf_num while issuing a
GET_PROFILE_CONFIG cmd as FW returns descriptors for all functions when
pf_num is zero. But, when pf_num is set to a non-zero value, FW does not
return the Port resource descriptor.
This patch fixes this by setting pf_num to 0 while issuing the query cmd
and adds code to pick the correct NIC resource descriptor from the list of
descriptors returned by FW.

The VF link state setting transition from "disable" to "auto" does not work
due to a bug in SET_LOGICAL_LINK_CONFIG_V1 cmd in FW. This issue could not
be fixed in FW due to some backward compatibility issues it causes with
some released drivers. The issue has been fixed by introducing a new
version (v2) of the cmd from 10.6 FW onwards. In v2, to set the VF link
state to auto, both PLINK_ENABLE and PLINK_TRACK bits have to be set to 1.
The VF link state setting feature now works on Lancer chips too from
FW ver 10.6.315.0 onwards.

The commit 435452aa8847 ("Prevent VFs from enabling VLAN promiscuous mode")
fixed the PF driver to not include the VLAN promisc capability while
provisioning the interface for a VF. But the fix did not remove this
capability from the profile descriptor of the VF. This causes the VF
driver to request this capability when it tries to create it's interface
at probe time. This could potentailly cause the VF probe to fail if the
FW enforces strict checking of the flags based on what was provisoned
by the PF. This strict checking is not being done by FW currently but
will be fixed in a future version. This patch fixes this issue by updating
the VF's profile descriptor so that they match the interface capability
flags provisioned by the PF.

The FW requires the pf_num field in the cmd hdr to be set for it to return
the specific function's descriptors in the GET_PROFILE_CONFIG cmd. If not
set, the FW returns the descriptors of all the functions on the device.
If the first descriptor is not what is being queried for, the driver will
read wrong data. This patch fixes this issue by using the GET_CNTL_ATTRIB
cmd to query the real pci_func_num of a function and then uses it in the
GET_PROFILE_CONFIG cmd.

The be_cmd_rx_filter() routine sends a non-embedded cmd to the FW and used
a pre-allocated dma memory to hold the cmd payload. This worked fine when
this cmd was synchronous. This cmd was changed to asynchronous mode by the
commit 8af65c2f4("make the RX_FILTER command asynchronous"). So now when
there are two quick invocations of this cmd, the 2nd request may end up
overwriting the first request, causing FW cmd corruption.
This patch reverts the offending commit and hence fixes the regression.

The SET_LOOPBACK_MODE command is always issued from ethtool only in a
process context. So, while waiting for the cmd to complete, the driver
can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done
by calling be_mcc_notify() instead of be_mcc_notify_wait() (that returns
only after the cmd completes while the MCCQ is locked).

this cmd and doesn't wait for a completion from the FW. If the FW/adapter
is in an error state, this change helps in not holding up the rtnl_lock

a response from the FW.

coherent dma memory is being allocated using either dma_alloc_coherent()
or the deprecated pci_alloc_consistent(). All these calls should be
changed to use dma_zalloc_coherent() to avoid uninitialized fields in
data structures backed by this memory.

OS2BMC feature will allow the server to communicate with the on-board
BMC/idrac (Baseboard Management Controller) over the LOM via
standard Ethernet.
When OS2BMC feature is enabled, the LOM will filter traffic coming
from the host. If the destination MAC address matches the iDRAC MAC
address, it will forward the packet to the NC-SI side band interface
for iDRAC processing. Otherwise, it would send it out on the wire to
the external network. Broadcast and multicast packets are sent on the
side-band NC-SI channel and on the wire as well. Some of the packet
filters are not supported in the NIC and hence driver will identify
such packets and will hint the NIC to send those packets to the BMC.
This is done by duplicating packets on the management ring. Packets
are sent to the management ring, by setting mgmt bit in the wrb header.
The NIC will forward the packets on the management ring to the BMC
through the side-band NC-SI channel.
