Hi, I am looking in the file hierarchy of dpdk, and I see that under /dpdk-1.7.1/lib/librte_eal/linuxapp/kni/ethtool we have: igb ixgbe README My question is: why the igb and ixgbe are on this path, under ethtool ? are they related to ethtool in any way ? The README does not explain it. Regards, Kevin
