Hi,

I found some bugreport on redhat and citrix about LRO problem

https://bugzilla.redhat.com/show_bug.cgi?id=773675 
https://bugzilla.redhat.com/show_bug.cgi?id=772317
http://support.citrix.com/article/CTX127400 

LRO is not supported with bridging, it can cause network slowdown and also kernel panic

redhat and ovirt disabled it by defautl


fix is : 

echo "options bnx2x disable_tpa=1" > /etc/modprobe.d/bnx2x.conf
echo "options mlx4_en num_lro=0" > /etc/modprobe.d/mlx4_en.conf
echo "options enic lro_disable=1" > /etc/modprobe.d/enic.conf
echo "options s2io lro=0" > /etc/modprobe.d/s2io.conf


I think it could be great to add it to proxmox default config
