From 44781fef1378969ea974b1b000ce7f3167eee459 Mon Sep 17 00:00:00 2001 From: Joao Pinto Date: Fri, 31 Mar 2017 14:22:02 +0100 Subject: net: stmmac: fix cbs configuration Sending again, because forgot to include net-dev. The QoS IP does not accept AVB capabilities to default/queue 0, this way we guarantee 75% bandwidth for AVB. This patch assures that only queues >= 1 gets CBS confgured. Additional info was also added to stmmac.txt. Reported-by: Niklas Cassel Signed-off-by: Joao Pinto Signed-off-by: David S.
