RDMA/mlx5: Fix drop packet rule in egress table
[ Upstream commit c73700806d4e430d182c2be069d230076818a99a ]
Initial drop action support missed that drop action can be added to egress
flow tables as well. Add the missing support.
This requires making sure that dest_type isn't set to PORT which in turn
exposes a possibility of passing dst while indicating number of dsts as
zero. Explicitly check for number of dsts and pass the appropriate
pointer.
