Is enabling hardware VLAN (802.1q) insertion possible with this family? The datasheet for the 82599 seems to indicate it's supported by the NIC, but I get -ENOTSUP when trying to call rte_eth_dev_set_vlan_pvid(). If it's just not implemented, are there any pointers for how to implement this in drivers/net/ixgbe/ixgbe_ethdev.c? Thanks, Cody
