Subject: [PATCH rdma-next 3/3] IB/ipoib: Change number of TX wqe to 64
Date: Mon, 16 Oct 2017 08:49:01 +0300 [thread overview]
Message-ID: <20171016054901.32479-4-leon@kernel.org> (raw)
In-Reply-To: <20171016054901.32479-1-leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>
From: Erez Shitrit <erezsh-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>
NAPI budget is 64 packets, while maximum polling size for
the send CQ is 16. Let's bring them in sync, so the NAPI
budget will be reused completely.
