After I shutdown switch port, a call for rte_eth_link_get() crashes with SEGFAULT. Apparently, ixgbe_dev_link_update() calls for non-existing in VF driver ixgbe_get_link_capabilities(). Is there a patch with get_link_capabilities() implementation for IXGBE VF I can use ? or Can I safely disable call for ixgbe_get_link_capabilities() for VF ?
