From: Stephen Hemminger Date: Thu, 27 Sep 2007 19:32:44 +0000 (-0700) Subject: sky2: FE+ vlan workaround X-Git-Tag: v2.6.23-rc9~21^2~2 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=d6c9bc1ed4301cbc3df4565ff5348b64bf2a767c;p=linux-2.6-omap-h63xx.git 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.
