    Subject[PATCH 4.14 63/94] hv_netvsc: Remove "unlikely" from netvsc_select_queue
    Date
    From: Haiyang Zhang <haiyangz@microsoft.com>

    commit 4d820543c54c47a2bd3c95ddbf52f83c89a219a0 upstream.

    When using vf_ops->ndo_select_queue, the number of queues of VF is
    usually bigger than the synthetic NIC. This condition may happen
    often.
    Remove "unlikely" from the comparison of ndev->real_num_tx_queues.

    Fixes: b3bf5666a510 ("hv_netvsc: defer queue selection to VF")
