In one error condition dm9000_parse_dt() returns NULL, however the
return value is checked using IS_ERR() in dm9000_probe(), leading to the
error not being properly propagated if CONFIG_OF is not enabled or the
device tree data is not available. Fix this by also returning an
ERR_PTR() in this case.

If the hw is in ALDPS mode, the hw may have no response for accessing
the most registers. Therefore, the ALDPS should be disabled before
accessing the hw in rtl_ops.init(), rtl_ops.disable(), rtl_ops.up(),
and rtl_ops.down(). Regardless of rtl_ops.enable(), because the hw
wouldn't enter ALDPS mode when linking on. The hw would enter the
ALDPS mode after several seconds when link down occurs and the ALDPS
is enabled.

We cannot make struct qdisc_skb_cb bigger without impacting IPoIB,
or increasing skb->cb[] size.
Commit e0f31d849867 ("flow_keys: Record IP layer protocol in
skb_flow_dissect()") broke IPoIB.
Only current offender is sch_choke, and this one do not need an
absolutely precise flow key.
If we store 17 bytes of flow key, its more than enough. (Its the actual
size of flow_keys if it was a packed structure, but we might add new
fields at the end of it later)

TG3 appears to have an issue performing TSO and checksum offloading
correclty when the frame has been vlan encapsulated (non-accelrated).
In these cases, tcp checksum is not correctly updated.
This patch attempts to work around this issue. After the patch,
802.1ad vlans start working correctly over tg3 devices.

Since commit 412ca1550cbe ("macvlan: Move broadcasts into a work queue"), the
driver uses tx_queue_len of the master device as the limit of packets enqueuing.
Problem is that virtual drivers have this value set to 0, thus all broadcast
packets were rejected.
Because tx_queue_len was arbitrarily chosen, I replace it with a static limit
of 1000 (also arbitrarily chosen).

LIBFC depends upon SCSI_FC_ATTRS and select's CRC32C.
The only alternative would be to 'select' CRC32C and all of
SCSI_FC_ATTRS direct and indirect dependencies in the Kconfig section
for every LIBFCOE user which makes little sense.
Subsequently, use 'depends' instead of 'select' for LIBFCOE too.

I cannot move a macvlan interface created on top of a bonding interface
to a different namespace:
% ip netns add dummy0
% ip link add link bond0 mac0 type macvlan
% ip link set mac0 netns dummy0
RTNETLINK answers: Invalid argument
%
The problem seems to be that commit f9399814927a ("bonding: Don't allow
bond devices to change network namespaces.") sets NETIF_F_NETNS_LOCAL
on bonding interfaces, and commit 797f87f83b60 ("macvlan: fix netdev

to inherit its features from the lower device.

fix several issues in sparc BPF JIT compiler.
ldx/stx related:
. classic BPF instructions that access mem[] slots were not setting
SEEN_MEM flag, so stack wasn't allocated. Fix that by advertising
correct flags
. LDX/STX instructions were missing SEEN_XREG, so register value
could have leaked to user space. Fix it.
. since stack for mem[] slots is allocated with 'sub %sp' instead
of 'save %sp', use %sp as base register instead of %fp.
. ldx mem[0] means first slot in classic BPF which should have
-4 offset instead of 0.
. sparc64 needs 2047 stack bias as per ABI to access stack
. emit_stmem() was using LD32I macro instead of ST32I
SKF_AD_VLAN_TAG* related:
. SKF_AD_VLAN_TAG_PRESENT must return 1 or 0 instead of '> 0' or 0
as per classic BPF de facto standard
. SKF_AD_VLAN_TAG needs to mask the field correctly

After sending a RTR frame the TX mailbox becomes a RX_EMPTY mailbox. To avoid
side effects when the RX-FIFO is full, this patch puts the TX mailbox into
TX_INACTIVE mode in the transmission complete interrupt handler. This, of
course, leaves a race window between the actual completion of the transmission
and the handling of tx-complete interrupt. However this is the best we can do
without busy polling the tx complete interrupt.

This patch implements the workaround mentioned in ERR005829:
ERR005829: FlexCAN: FlexCAN does not transmit a message that is enabled to
be transmitted in a specific moment during the arbitration process.
Workaround: The workaround consists of two extra steps after setting up a
message for transmission:
Step 8: Reserve the first valid mailbox as an inactive mailbox (CODE=0b1000).
If RX FIFO is disabled, this mailbox must be message buffer 0. Otherwise, the
first valid mailbox can be found using the "RX FIFO filters" table in the
FlexCAN chapter of the chip reference manual.
Step 9: Write twice INACTIVE code (0b1000) into the first valid mailbox.

Reported by Nikolay Aleksandrov. In efx_init_port() we call
efx_mac_reconfigure() to work around a Falcon/A1 limitation, and this calls
efx_{arch}_filter_sync_rx_mode(), which takes the addr_list_lock; but this
lock is uninitialised, because we haven't called register_netdevice() yet.
So, in efx_farch_filter_sync_rx_mode(), check efx_dev_registered() before
doing anything else.
The EF10 equivalent, efx_ef10_filter_sync_rx_mode(), already has the
corresponding check.

Just like CNIC, tristate of these two modules is also dependent on IPV6.
These need to be handled separately as they select CNIC, which can override
tristate for CNIC from 'm' to 'y', which can cause build failures when ipv6 is
compiled as a module even if CNIC's Kconfig will only 'm' or 'n' when ipv6 is
compiled as a module.

Currently, it is possible to modify the vlan filter
configuration to add pvid or untagged support.
For example:
bridge vlan add vid 10 dev eth0
bridge vlan add vid 10 dev eth0 untagged pvid
The second statement will modify vlan 10 to
include untagged and pvid configuration.
However, it is currently impossible to go backwards
bridge vlan add vid 10 dev eth0 untagged pvid
bridge vlan add vid 10 dev eth0
Here nothing happens. This patch correct this so
that any modifiers not supplied are removed from
the configuration.

The bridge code checks if vlan filtering is enabled on both
ingress and egress. When the state flip happens, it
is possible for the bridge to currently be forwarding packets
and forwarding behavior becomes non-deterministic. Bridge
may drop packets on some interfaces, but not others.
This patch solves this by caching the filtered state of the
packet into skb_cb on ingress. The skb_cb is guaranteed to
not be over-written between the time packet entres bridge
forwarding path and the time it leaves it. On egress, we
can then check the cached state to see if we need to
apply filtering information.

The problem is that the slave is first linked and slave_cnt is
incremented afterwards leading to a div by zero in the modes that use it
as a modulus. What happens is that in bond_start_xmit()
bond_has_slaves() is used to evaluate further transmission and it becomes
true after the slave is linked in, but when slave_cnt is used in the xmit
path it is still 0, so fetch it once and transmit based on that. Since
it is used only in round-robin and XOR modes, the fix is only for them.
Thanks to Eric Dumazet for pointing out the fault in my first try to fix
this.

If the parameter "features" of __rtl8169_set_features() is equal to
dev->features, the variable "changed" is alwayes 0, and nothing would
be changed.
