The be2net driver performs fw temperature queries on be_worker() routine,
which is executed each second for each be_adapter. There is a frequency
threshold to avoid fw query to happens at each call to be_worker();
instead, currently a fw query occurs once in 64 runs of the procedure.
Nevertheless, this fw temperature query is invoked only for adapters which
interface is up, so we can see I/O errors on read of hwmon counters from
userspace (from tools like lm-sensors) in case we have adapters' functions
which interface is down.
This patch moves the fw query code to be invoked even if interface is down.
No functional changes were introduced.

The workqueue health->wq was used as per device private health thread.
This was done to perform delayed work.
The workqueue has a single workitem(&health->work) and
hence doesn't require ordering. It is involved in handling the health of
the device and is not being used on a memory reclaim path.
Hence, the singlethreaded workqueue has been replaced with the use of
system_wq.
Work item has been flushed in mlx5_health_cleanup() to ensure that
there are no pending tasks while disconnecting the driver.

- Since ndev is not ready, added set_irq_name to set irq name
- Since ndev is not ready, changed mdio_bus->parent to pdev->dev
- Replaced netif_start(stop)_queue by netif_tx_start(stop)_queues
- Removed napi_del call since it's called by free_netdev
- Added dev_close call, within remove

Such a big dump of register values is hardly useful on a production
system.
Another downside of the now removed functions is that calling
emac_dump_regs resulted in at least 87 calls to dev_info while holding a
spinlock and having irqs off which is a big source of latency.

Add support for query the minimum inline mode from the Firmware.
It is required for correct TX steering according to L3/L4 packet
headers.
Each send queue (SQ) has inline mode that defines the minimal required
headers that needs to be copied into the SQ WQE.
The driver asks the Firmware for the wqe_inline_mode device capability
value. In case the device capability defined as "vport context" the
driver must check the reported min inline mode from the vport context
before creating its SQs.

inline headers in the SQ WQE.
Before sending each packet check that the minimum required headers
on the WQE are copied.

10GbE Intel Wired LAN Driver Updates 2016-07-22
This series contains updates to ixgbe and ixgbevf only.
Emil fixes the NACK check in ixgbevf_set_uc_addr_vf() for instances where
the index is not equal to zero. Fixes an issue where mac->ops.setup_fc
can be NULL for backplanes which can cause the driver to crash on load.
Don fixes the second parameter of the LED functions, which is the index to
the LED we are interested in affecting. Fixed variable to store register
reads to unsigned integer. Adds support for the new x553 hardware into
ixgbevf. Fixed a missing rtnl lock around ixgbevf_reinit_locked().
Fixed an issue where in ixgbevf_reset_subtask() was not verifying that
the port has been removed. Cleans up the initial crosstalk fix, since
the SFP that indicates the presence of a SFP+ module changes between
hardware types.
Babu Moger fixes typo in freeing IRQ, since the array subscript increments
after the execution of the statement.
Wei Yongjun adds the missing destroy_workqueue() before returning from
ixgbe_init_module() in the error handling case.
Tony adds range checking for setting the MTU from the VF, where the PF can
return a NACK but this was not passed on to the VF, so propagate the
results from the PF to the VF so errors can be reported. Consolidates
mailbox read and write functions, since the recent changes to
ixgbevf_write_msg_read_ack(), other functions are performing the same
operations done here.
Colin Ian King removes a redundant check on ret_val, since ret_val has
not changed since the previous check.

====================
40GbE Intel Wired LAN Driver Updates 2016-07-22
This series contains updates to i40e and i40evf.
Heinrich Schuchardt found a possible null pointer being dereferenced in
i40e_debug_aq(), fixed the issue by doing the variable assignment after
we are sure the pointer is not null.
Avinash fixed an issue when link was down, we were not showing the
correct advertised link modes.
Mitch cleans up a useless initializer since the variable is assigned
right away. Refactors the receive filter handling to properly track
filter adds and deletes so the driver will not lose filters during a
reset and up/down cycles. Also added a tracking mechanism so that the
driver knows when to enter and leave promiscuous mode.
Catherine removes a device id which is not needed (or used). Moves
a mutex lock since we need to lock the client list around the
i40e_client_release() call to prevent the release from interrupting
the client instances while they are being added.
Joshua adds Hyper-V specific VF device ids.
Amitoj Kaur Chawla cleans up a redundant memset() call before a memcpy().
Stefan Assmann adds the missing link advertise for some x710 NICs.
Tushar Dave fixes and issue found on SPARC, where a PF reset clears MAC
filters and if a platform-specific MAC address is used, the driver has
to explicitly write default MAC address to MAC filters otherwise all
incoming traffic destined to the default MAC address will be dropped
after reset.

Add common library module(libcxgb.ko) for
Chelsio drivers to remove duplicate code.
Code for iSCSI DDP Page Pod Manager is moved
from cxgb4.ko to libcxgb.ko. Earlier only cxgbit.ko
was using this code, now cxgb3i and cxgb4i will
also use common Page Pod manager code.
In future this module will have common connection
management and hardware specific code that can be
shared by multiple Chelsio drivers.

This patch offloads port mirroring directives to hw using the matchall TC
with action mirror. It includes both the implementation of the
ndo_setup_tc function for the spectrum driver and the spectrum hardware
offload configuration code.
The hardware offload code is basically two new functions which are capable
of adding and removing a new mirror ports pair. It is done using the MPAT,
MPAR and SBIB registers:
- A new Switch-Port Analyzer (SPAN) entry is added using MPAT to the 'to'
port.
- The 'to' port is bound to the SPAN entry using MPAR register.
- In case of egress SPAN, the 'to' port gets a new internal shared
buffer using SBIB register.
In addition, a new database was added to the mlxsw_sp struct to store all
the SPAN entries and their bound ports list. The number of supported SPAN
entries is determined by resource query.

This patch address a few issues with the initial crosstalk fix. Most
important of which is the SDP that indicates the presents of a SFP+
module changes between HW types. With this change that is taken in
to consideration
It also moves the check closer to the base code that checks link. This
makes it so we only need to do the check in one spot.

Currently when setting the VF's MTU, the PF can return a NACK but this
isn't passed on to the VF. Propagate the results from the PF to the VF
so errors can be reported.
In ixgbevf_change_mtu, return an error and reject the change.
For ixgbevf_configure_rx, log the error for debugging purposes since
the function is buried in a series of Rx config routines that are void.
