>Description:
The man page for bce(4) lists under bugs that there is no vlan
support. This is actually not true. I just never tracked down in the
spec if all special cases that use extra bytes are covered. But
since I don't think we use these special cases, it would probably
be fine to remove this statement, as the bce driver has always
had support for the increased mtu.

should the man page be changed to "There is no hardware VLAN support"
then ?

I think the hardware does support it. However bce(4) doesn't
have ETHERCAP_VLAN_MTU enabled. Testing I've done (with the
BCM4400 core in the BCM5365) shows ETHERCAP_VLAN_MTU to work
fine, but the real BCM4401 might be slightly different.

Pending testing on a typical PCI-attached BCM440x core, I propose adding
ETHERCAP_VLAN_MTU in the driver, and removing the note in the man page.

I think this should work. BCE_RX_MAX/BCE_TX_MAX is the max
packet length registers, which are set to 32 bytes over 1518
which accounts for a broadcom 28 byte header(rx_pph), leaving 4 bytes for vlan tag.
