Subject: [PATCH net 1/2] cxgb4: Fix work request size calculation for loopback test
Date: Tue, 18 Aug 2020 21:10:57 +0530 [thread overview]
Message-ID: <20200818154058.1770002-2-ganji.aravind@chelsio.com> (raw)
In-Reply-To: <20200818154058.1770002-1-ganji.aravind@chelsio.com>
Work request used for sending loopback packet needs to add
the firmware work request only once. So, fix by using
correct structure size.
Fixes: 7235ffae3d2c ("cxgb4: add loopback ethtool self-test")
