Problem? 802.1q kernel 2.4.18-rc1-rmap12f

Problem? 802.1q kernel 2.4.18-rc1-rmap12f

[Teodor Iacob]

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?


Respectfully,
Teodor Iacob

Did you patch the ethernet driver so that it supports the bigger
MTUs needed for VLAN support ? It's all described in the VLAN patch docs.

Is there any drawback to use this patch? :
In const char i82557_config_cmd[22] = {
-       0x68, 0, 0x40, 0xf2, 0xBD,              /* 0xBD->0xFD=Force
full-duplex */
+       0x68, 0, 0x40, 0xfa, 0xBD,              /* 0xBD->0xFD=Force
full-duplex */


I use the other 2 interfaces in normal mode and they are eepro100 too,
only one uses 2 tagged subinterfaces.

Btw, I was able to reconfigure the whole thing and it does work fine now,
but I can't really make a test now with the other two interfaces since I
did all this remotely.

AFAIK you have to change 2 values in this section: the second and third
occurences of 0xf2 to 0xfa.
