Subject: [PATCH rdma-next v1 3/3] RDMA: Fix link active_speed size
Date: Wed, 2 Sep 2020 10:45:03 +0300 [thread overview]
Message-ID: <20200902074503.743310-4-leon@kernel.org> (raw)
In-Reply-To: <20200902074503.743310-1-leon@kernel.org>
From: Aharon Landau <aharonl@mellanox.com>
According to the IB spec active_speed size should be u16 and not u8 as
before. Changing it to allow further extensions in offered speeds.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
