Subject: [net V2 03/15] net/mlx5: DR, Allow old devices to use multi destination FTE

From: Erez Shitrit <erezsh@...dia.com>

The current check isn't aware of old devices that don't have the
relevant FW capability. This patch allows multi destination FTE
in old cards, as it was before this check.

Fixes: f6f46e7173cb ("net/mlx5: DR, Add check for multi destination FTE")
