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 Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
