Subject: [net-next 08/17] net/mlx5e: Remove redundant match on tunnel destination mac

From: Vlad Buslov <vladbu@...dia.com>

Remove hardcoded match on tunnel destination MAC address. Such match is no
longer required and would be wrong for stacked devices topology where
encapsulation destination MAC address will be the address of tunnel VF that
can change dynamically on route change (implemented in following patches in
the series).
