[E1000-devel] Huge Performance Regression with adding of IXGBE_FLAG_IN_NETPOLL flag

2013-09-02 Thread Shyam Kaushik
Gregory et al, We recently moved to using Linux kernel 3.8 & hence had to use ixgbevf driver version 2.7.12-k. We realized that we have a huge performance regression in most of the cases. Our setup involves: # ixgbevf driver over SRIOV VF # SCST iSCSI target exposing standard linux RAMdisk
