Subject: [PATCH 1/2] amd-xgbe: Fix mask appliciation for Clause 37 register
Date: Mon, 14 Nov 2016 16:28:49 -0600	[thread overview]
Message-ID: <20161114222849.25160.71951.stgit@tlendack-t1.amdoffice.net> (raw)
In-Reply-To: <20161114222827.25160.24791.stgit@tlendack-t1.amdoffice.net>

The application of a mask to clear an area of a clause 37 register value
was not properly applied. Update the code to do the proper application
of the mask.
