>Description:
Broadcom netcard described above doesn't work with
vlans if hardware vlans turned on in driver. It works fine
if vlans not used. Since bge(4) doesn't support turning
vlanhwtag off (via ifconfig), the only workarround is to
patch driver.
>How-To-Repeat:
Try to use vlans on that hardware.
>Fix:
Workaround: turn off hardware vlan tagging in driver.
