====================
mlx5-updates-2020-08-03
This patchset introduces some updates to mlx5 driver.
1) Jakub converts mlx5 to use the new udp tunnel infrastructure.
Starting with a hack to allow drivers to request a static configuration
of the default vxlan port, and then a patch that converts mlx5.
2) Parav implements change_carrier ndo for VF eswitch representors,
to speedup link state control of representors netdevices.
3) Alex Vesker, makes a simple update to software steering to fix an issue
with push vlan action sequence
4) Leon removes a redundant dump stack on error flow.
