Saeed Mahameed:

====================
mlx5e-updates-2018-12-10 (gre)

This patch set adds GRE offloading support to Mellanox ethernet driver.

Patches 1-5 replace the existing egdev mechanism with the new TC indirect
block binds mechanism that was introduced by Netronome:
7f76fa36 ("net: sched: register callbacks for indirect tc block binds")

Patches 6-9 add GRE offloading support along with some required
refactoring work.

Patch 10, Add netif_is_gretap()/netif_is_ip6gretap()
 - Changed the is_gretap_dev and is_ip6gretap_dev logic from structure
   comparison to string comparison of the rtnl_link_ops kind field.

Patch 11, add GRE offloading support to mlx5.

Patch 12 removes the egdev mechanism from TC as it is no longer used by
any of the drivers.
