From cafdc45c949b9963cbfb8fe3a68d0ab16b0208ce Mon Sep 17 00:00:00 2001 From: John Crispin Date: Thu, 15 Sep 2016 16:26:40 +0200 Subject: net-next: dsa: add Qualcomm tag RX/TX handler Add support for the 2-bytes Qualcomm tag that gigabit switches such as the QCA8337/N might insert when receiving packets, or that we need to insert while targeting specific switch ports. The tag is inserted directly behind the ethernet header. Reviewed-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: John Crispin Signed-off-by: David S.
