Hello, I am trying to enable RSC/LRO on a VF (X540-AT2 based) which has been PCIe passthrough'd to a Ubuntu VM (12.10) running latest ixgbevf. The host machine is a dual socket E5-2600 machine with a bunch of dual port X540 cards, running RHEL 6.2 Linux. I am using ixgbe 3.15.1 on the host and have enabled SR-IOV. I cannot seem to find a way to enable RSC/LRO in the guest OS on the VF (ethtool on the guest ixgbevf does not let me do it). On looking into ixgbe driver it seems that it disables RSC/LRO in ixgbe_enable_sriov() function. My questions are -
1. It appears per X540 data sheet that enabling RSC on a VF should be a supported option. IIUC this is a driver limitation. Am I correct ? 2. If this is indeed a driver limitation then, I'd request if you could point me to a driver patch or another way to overcome this (I am willing to code up a patch if someone can point me to the solution.) Highly appreciate your help! Thanks, Chaitanya ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
