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!
