From 396138f03f4521c55ecc3a5dd75d4c56e6323244 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Tue, 7 Oct 2008 13:46:07 +0000 Subject: dsa: add support for Trailer tagging format This adds support for the Trailer switch tagging format. This is another tagging that doesn't explicitly mark tagged packets with a distinct ethertype, so that we need to add a similar hack in the receive path as for the Original DSA tagging format.
