RCA : Mostly nic flap when burst of traffic comes .The NIC reset is initated by dpdk and it fires the command as the VF, There is no mechanism from PF to VF singal that NIC reset is Succesful .The VF waits for certain time and then start to fire command to PF and if that command is not execuated , it will go in pending state and will become deadlock situation .
Fix. Added VF reset status check facility to fire command after nic reset is done to avoid race condition .
QA validation is done . Issue not seen with the driver.
Vf command failing is resolved
