Subject: [PATCH net-next 03/20] net: Add ndo_queue_create callback

From: David Wei <dw@...idwei.uk>

Add ndo_queue_create() to netdev_queue_mgmt_ops that will create a new
rxq specifically for mapping to a real rxq. The intent is for only
virtual netdevs i.e. netkit and veth to implement this ndo. This will
be called from ynl netdev fam bind-queue op to atomically create a
mapped rxq and bind it to a real rxq.
