Cannot set mtu 9000 after upgrade to kernel 2.6.32-32-pve

[acidrop]

Hello!

I have problem setting mtu 9000 on a nic on one of two proxmox nodes after upgrading to kernel 2.6.32-32-pve.If I rollback to kernel 2.6.32-31-pve there is not such issue.

Below is some info:

Is this a driver issue?

thank you

seem to be a driver bug,

"SIOCSIFMTU: Invalid argument" said that mtu 9000 is too big for your nic.

Is there a way to troubleshoot it or just I have to rollback to previous kernel?
