Ben, I enabled vlan in the eth mac by writing to vlan1tag and adjust mtu

vlan. Now, when I ping from a remote pc which also has vlan enabled
interface,
I don't see vlan tags in the frames. Same issue if I ping the remote PC.
Basically,
I don't see vlan tag in tx/rx directions.
Show me ifconfig -a on the VLAN machine, and what commands
you are using to ping.
If you want to give me ssh access to the system, I'll log
in and take a look..
Thanks,
Ben

Ben,
Thanks for your response. The mac data sheet says, when 0x8100 is
written to the
van1_tag register, the mac compares 13th & 14th bytes of incoming
frame and, if it
finds a match, it sets vlan1 bit in rx status register. However,
this particular status
bit is not actually exposed to driver access. The documentation
could be wrong.
Other than the above, no behaviour changes. In this case, I just
simply ensure
that the driver/chip can handle MTU + 4 bytes? No need to enable
NETIF_VLAN_HW_TX/RX
and related callbacks?
By the way, I don't see my postings @
http://ns2.lanforge.com/pipermail/vlan/2007-March/thread.html

'm trying to enable VLAN in my eth driver. The eth mac supports

not have any other vlan related registers or anything else. It
does not give
any indication during rx if VLAN pkts received.
How do I enable VLAN in my driver for such a MAC? I'm basically
confused with all the callbacks such as vlan_rx_register etc most
drivers support.
Currently, in my driver I've enabled the features
NETIF_VLAN_HW_TX/RX
and providing the above callbacks. But I'm not sure whether
these flags
are applicable to my driver.
what else I need to do? I'm kinda stuck here. Any help would be
highly
appreciated.
thx
