How reproducible:
100%

Steps to Reproduce:
(on both back-to-back connected servers do)
modprobe 8021q
insmod bnx2x/src/bnx2x.ko
modprobe bonding mode=6 miimon=100
ifconfig bond0 up
ifenslave bond0 eth4 #port one of 57711 device
ifenslave bond0 eth5 #port two of 57711 device
vconfig add bond0 7
ifconfig bond0.7 192.168.10.${SERVIP}
try to ping machine with RH55
