Merge tag 'mlx5-updates-2018-10-03' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux 

Saeed Mahameed says:

====================
mlx5-updates-2018-10-03

mlx5 core driver and ethernet netdev updates, please note there is a small
devlink releated update to allow extack argument to eswitch operations.

From Eli Britstein,
1) devlink: Add extack argument to the eswitch related operations
2) net/mlx5e: E-Switch, return extack messages for failures in the e-switch devlink callbacks
3) net/mlx5e: Add extack messages for TC offload failures

From Eran Ben Elisha,
4) mlx5e: Add counter for aRFS rule insertion failures

From Feras Daoud
5) Fast teardown support for mlx5 device
This change introduces the enhanced version of the "Force teardown" that
allows SW to perform teardown in a faster way without the need to reclaim
all the FW pages.
Fast teardown provides the following advantages:
    1- Fix a FW race condition that could cause command timeout
    2- Avoid moving to polling mode
    3- Close the vport to prevent PCI ACK to be sent without been scatter
    to memory
