Subject: [PATCH rdma-next 2/2] IB/mlx5: Enlarge autogroup flow table
Date: Wed, 29 Mar 2017 06:09:01 +0300	[thread overview]
Message-ID: <20170329030901.5772-2-leon@kernel.org> (raw)
In-Reply-To: <20170329030901.5772-1-leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

From: Maor Gottlieb <maorg-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

In order to enlarge the flow group size to 8k, we decrease
the number of flow group types to 6 and increase the flow
table size to 64k.

Flow group size is calculated as follow:
  group_size = table_size / (#group_types + 1)

Fixes: 038d2ef87572 ('IB/mlx5: Add flow steering support')
