From: Maor Gottlieb <maorg@xxxxxxxxxx>
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.
Fixes: f29de9eee782 ("RDMA/mlx5: Add support for drop action in DV steering")
