Hi Antoni,
The problem is LRO activated on bnx2x driver.
After the reboot the LRO comes activated, after reconfiguring the bond
the LRO is deactivated.
So i created /etc/modprobe.d/bnx2x.conf with: options bnx2x
disable_tpa=1
and everythink is ok now after reboot.
There was a previous bug open for RHEL5 about this problem
https://bugzilla.redhat.com/show_bug.cgi?id=518531 should i reopen this
for RHEL6?
This problem only happens when bnx2x is used with bonds... should this
be considered as a bug?
Best regards,
Ricardo Esteves.

pastebin of a 'vdsClient 0 getVdsCaps' (or 'vdsClient -s 0 getVdsCaps'
if
the first doesn't work)
from the host when the bond is slow, and one after you break and create it
again?
if you don't have vdsClient command you can 'yum install vdsm-cli' and it
should be available. > > > > > > > -----Original Message----- >
