qeth reports "Could not set up broadcast filtering on eth0: 0x2, continuing"
Last modified: 2007-11-30 17:06:57 EST
Description of problem:
Broadcast support appears to be broken for qeth.
According to Linux on IBM eserver zSeries and S/390: TCP/IP Broadcast on z/VM
Guest LAN (specifically page 14 of the pdf at
http://www.redbooks.ibm.com/redpapers/pdfs/redp3596.pdf), the revision # of the
qeth driver provided by taroon is one that should support broadcast.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Have modules.conf, chandev.conf, and eth0 configured by installer for qeth
(Guest LAN) support
2. Boot image, watch messages
Error message indicates that broadcast was not supported
No error message
snip of dmesg shows:
qdio: loading QDIO base support version 2 ($Revision: 1.145 $/$Revision: 1.66 $)
qeth: loading qeth S/390 OSA-Express driver ($Revision: 1.337 $/$Revision: 1.113
$/$Revision: 1.42 $:VLAN)
qeth: allocated 0 spare buffers
qeth: unknown parameter: -0x072A
qeth: Trying to use card with devnos 0x728/0x729/0x72A
qeth: Device 0x728/0x729/0x72A is an OSD Express card (level: 3132)
with link type Gigabit Eth (no portname needed by interface)
divert: allocating divert_blk for eth0
qeth: VLAN not supported on eth0
qeth: IPv6 not supported on eth0
qeth: Could not set up broadcast filtering on eth0: 0x2, continuing
I got the same message with the 2.4.21-1.1931.2.349.2.2.ent kernel too
VLAN is supported by the drivers we ship. "VLAN not supported" means you either
have a downlevel z/VM or have not done the configuration correctly.
I do not have access to a working VLAN configuration, so I can not check this.
Are you sure z/VM and your configuration are all correct?

In particular, is APAR VM63172 present?
Ugh, our VM sysprog informed me that APAR VM63172 hasn't been applied. He's
working on ordering the maintenance pack. Sorry for the false alert, hopefully
that will clear up the problem.
PTF UM30652 resolves the APAR.
I just verified that it works (was broken before, works now)
I'm running .411 kernel ok.
Can this be closed now?
Thank you for veryfing it in your lab, feel free to close (our z/VM sysprog is
still working on getting the PTF).
Setting to modified so you can confirm when your z/vm instance gets the ptf
The latest maintenance went on over the weekend, it's working now.
Daniel forgot to close - closing now.
