Subject: RE: Realtek r8168C / r8169 driver VLAN TAG stripping


I have tested 8168C with RTL_GIGA_MAC_VER_22 . It seems fine with VLAN. My
platform is using Fedora 14. I connect my linux platform with windows one
directly because I don't have a switch supporting VLAN. I set VLAN both windows
side and Linux side and it works well. For the windows side, I use 8111D.
