Problem? 802.1q kernel 2.4.18-rc1-rmap12f

[Teodor Iacob <theo@astral.kappa.ro>]

Hello,

I shall describe the hardware involved and the layout first:
A PC router i815 Motherboard, 3 Intel Etherexpress PRO 100 82557
Allied Telesyn AT-8224XL 802.1q capable.

Software: Slackware 8.0, kernel 2.4.18-rc1-rmap12f.

I want to use the eth0 as 2 subinterfaces with 802.1q with vlan IDs 3 and
5, so this is how I set the whole thing up:

/sbin/ifconfig eth0 up # This to make the link of the interface up
vconfig add eth0 5
vconfig add eth0 3

/sbin/ifconfig eth0.5 inet ..etc..
/sbin/ifconfig eth0.3 inet ...etc..

and I have also the default gateway through the eth0.5 vlan.

Now after a fresh start, I can ping whatever I want, but I cannot start a
file transfer, it just locks up after first 1024 bytes ( as seen with tick
in simple ftp command ).

If I change the startup scripts and ofc the aty switch to not use tagging
on the interface and use simple eth0 the transfer is ok. Now I get the
vlan back and the transfer works, but if I restore the configurations and
reboot the machine I cannot make transfers. I was able to ping -s 1400
stations through this 802.1q, but I didn't test further up (1467
or more ..etc.).

Does anybody can help me track this thing? Could this be kernel related?
