Merge branch '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue



Jeff Kirsher says:

====================
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.
