    be2net: support TX batching using skb->xmit_more flag · 5f07b3c5
    Sathya Perla authored
    This patch uses skb->xmit_more flag to batch TX requests.
    TX is flushed either when xmit_more is false or there is
    no more space in the TXQ.
    
    Skyhawk-R and BEx chips require an even number of wrbs to be posted.
    So, when a batch of TX requests is accumulated, the last header wrb
    may need to be fixed with an extra dummy wrb.
    
    This patch refactors be_xmit() routine as a sequence of be_xmit_enqueue()
    and be_xmit_flush() calls. The Tx completion code is also
    updated to be able to unmap/free a batch of skbs rather than a single
    skb.
