Message-ID: <20170413115445.16662-2-manish.chopra@cavium.com>
Date: Thu, 13 Apr 2017 04:54:44 -0700
From: Manish Chopra <manish.chopra@...ium.com>

CC: <netdev@...r.kernel.org>, <Yuval.Mintz@...ium.com>
Subject: [PATCH net-next 1/2] qed: aRFS infrastructure support
This patch adds necessary APIs to interface with
qede aRFS support in successive patch.
It also reserves separate PTT entry for aRFS,
[as being in fastpath flow] for hardware access instead of
trying to acquire it at run time from the ptt pool.
