From: Luca Boccassi <bl...@debian.org> These patches were originally sent by Wenzhuo Lu:
http://dpdk.org/dev/patchwork/patch/14009/ http://dpdk.org/dev/patchwork/patch/14010/ http://dpdk.org/dev/patchwork/patch/14011/ The current rte_eth_dev_reset API does not correctly reset the VF when the PF flaps on the host. With these patches, at least the ixgbe driver with a X540 card (Linux kernel 4.9 on the host) appears to work correctly. The test is as simple ip link down/up on the host, and then check that traffic still flows through the VF in the guest. I am not an expert in these PMDs hence the RFC mark - I would like to ask for feedback and help from the PMD maintainers and developers. Thanks!
