Re: Jumbo frame Debian Wheezy.

[Muhammad Yousuf Khan <sirtcp@gmail.com>]

Another finding is that i can change the mtu less then 1500  my system is dell precision 490. i have other system on squeeze with no issue at all. but they are on proxmox.

i have tested that i can set any value less then or equals to 1500 mtu but when i even try 1501 it says
SIOCSIFMTU: Invalid argument

i have same system working on proxmox. deployed on debian squeeze and i can go up to 9000 with no problem.
this  problem is  in non proxmox  system having debian wheezy with libvirt.

Please guide.

Thanks,

Yousuf
