Subject: [PATCH 23/78] wlcore/wl18xx: add hw op for Rx HW checksum
Date: Thu, 10 May 2012 12:13:28 +0300 [thread overview]
Message-ID: <1336641263-5761-24-git-send-email-arik@wizery.com> (raw)
In-Reply-To: <1336641263-5761-1-git-send-email-arik@wizery.com>
Some chip families can checksum certain classes of Rx packets in FW.
Implement the Rx-checksum feature as a HW-op. For the 18xx chip-family,
set Rx-checsum according to indication from FW.
