Would you try latest msk(4) in HEAD? I think you can download
if_msk.c and if_mskreg.h from HEAD and can build it on stable/8.
Due to added interface capabilities you have to add the following
code in the beginning of if_msk.c to build it on stable/8.

#ifndef IFCAP_VLAN_HWTSO
#define IFCAP_VLAN_HWTSO	0
#endif

Also show me the output of "devinfo -rv | grep phy".
