Subject: [PATCH net-next v4 03/10] net/mlx5e: Remove rq references in mlx5e_rx_am
Date: Tue, 9 Jan 2018 16:06:14 -0500 [thread overview]
Message-ID: <1515531981-14461-4-git-send-email-andy@greyhouse.net> (raw)
In-Reply-To: <1515531981-14461-1-git-send-email-andy@greyhouse.net>
From: Andy Gospodarek <gospo@broadcom.com>
This makes mlx5e_am_sample more generic so that it can be called easily
from a driver that does not use the same data structure to store these
values in a single structure.
