From d6c9bc1ed4301cbc3df4565ff5348b64bf2a767c Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Thu, 27 Sep 2007 12:32:44 -0700 Subject: sky2: FE+ vlan workaround The FE+ workaround means the driver can no longer trust the status register to indicate VLAN tagged frames. The fix for this is to just disable VLAN acceleration for that chip version. Tested and works fine.
