Subject: [PATCH v3 3/6] net/sfc: factor out function to report Rx capabilities
Date: Thu, 18 Jan 2018 07:07:46 +0000	[thread overview]
Message-ID: <1516259269-6887-4-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1516259269-6887-1-git-send-email-arybchenko@solarflare.com>

From: Ivan Malov <ivan.malov@oktetlabs.ru>

The patch adds a separate function to report supported
Rx capabilities because this function will be required
in more places across the code in the upcoming patches.
