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