-Subject: [PATCH] dpaa2-eth: Enable Rx PFC
-
-Instruct the hardware to respond to received PFC frames.
-
-Current firmware doesn't allow us to selectively enable PFC
-on the Rx side for some priorities only, so we will react to
-all incoming PFC frames (and stop transmitting on the traffic
-classes specified in the frame).
-
-PFC depends on the PAUSE flag also being set in link options.
-Don't set it implicitly when user configures PFC, but issue
-a warning if the two settings are not in sync.
-
-For the Tx side, setting the PFC_PAUSE flag in the link options
-is necessary but not sufficient, so PFC frame generation is
-not enabled yet.
-
