Subject: [PATCH] mlx4: Fixing Ethernet unicast packet steering
Date: Wed, 3 Aug 2011 17:21:00 +0300	[thread overview]
Message-ID: <4E39594C.4090808@mellanox.co.il> (raw)


For older FW versions, fixing the usage of per port Mac table.
For each port we must define the base QP number, which is passed
to the HW.
Setting the correct value in SET_PORT FW command to enable the steering.
