    xen-netback: Factor queue-specific data into queue struct · e9ce7cb6
    Wei Liu 提交于
    In preparation for multi-queue support in xen-netback, move the
    queue-specific data from struct xenvif into struct xenvif_queue, and
    update the rest of the code to use this.
    
    Also adds loops over queues where appropriate, even though only one is
    configured at this point, and uses alloc_netdev_mq() and the
    corresponding multi-queue netif wake/start/stop functions in preparation
    for multiple active queues.
    
    Finally, implements a trivial queue selection function suitable for
    ndo_select_queue, which simply returns 0 for a single queue and uses
    skb_get_hash() to compute the queue index otherwise.
