Subject: [PATCH rdma-next 2/8] RDMA/qedr: Fix doorbell setting
Date: Wed, 2 Sep 2020 19:57:35 +0300 [thread overview]
Message-ID: <20200902165741.8355-3-michal.kalderon@marvell.com> (raw)
In-Reply-To: <20200902165741.8355-1-michal.kalderon@marvell.com>
Change the doorbell setting so that the maximum value between
the last and current value is set. This is to avoid doorbells
being lost.
Fixes: a7efd7773e31 ("qedr: Add support for PD,PKEY and CQ verbs")
