From b21290b77f78f62e3f41ef876bfadacd65c83980 Mon Sep 17 00:00:00 2001 From: Yuval Mintz Date: Wed, 27 Jul 2016 14:45:21 +0300 Subject: [PATCH] qed: Don't over-do producer cleanup for Rx Before requesting the firmware to start Rx queues, driver goes and sets the queue producer in the device to 0. But while the producer is 32-bit, the driver currently clears 64 bits, effectively zeroing an additional CID's producer as well. Signed-off-by: Yuval Mintz Signed-off-by: David S.
