    net/mlx4_en: Ignore budget on TX napi polling · fbc6daf1
    Amir Vadai authored
    It is recommended that TX work not count against the quota.
    The cost of TX packet liberation is a minute percentage of what it costs to
    process an RX frame. Furthermore, that SKB freeing makes memory available for
    other paths in the stack.
    
    Give the TX a larger budget and be more aggressive about cleaning up the Tx
    descriptors this budget could be changed using ethtool:
    $ ethtool -C eth1 tx-frames-irq <budget>
