Merge branch 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux
1) New generic devlink param "enable_roce", for downstream devlink
reload support
2) Do vport ACL configuration on per vport basis when
enabling/disabling a vport. This enables to have vports enabled/disabled
outside of eswitch config for future
3) Split the code for legacy vs offloads mode and make it clear
4) Tide up vport locking and workqueue usage
5) Fix metadata enablement for ECPF
6) Make explicit use of VF property to publish IB_DEVICE_VIRTUAL_FUNCTION
7) E-Switch and flow steering core low level support and refactoring for
netfilter flowtables offload
