For the record, this is in fact due to a difference in the OpenBSD driver, i.e., it does not apply to FreeBSD. OpenBSD does not enable VLAN tag stripping in hardware. Without this, the chip apparently does not perform any rx checksumming on tagged frames. -- Christian "naddy" Weisgerber naddy@mips.inka.de
