ethtool: add tx aggregation parameters
Add the following ethtool tx aggregation parameters: ETHTOOL_A_COALESCE_TX_AGGR_MAX_BYTES Maximum size in bytes of a tx aggregated block of frames. ETHTOOL_A_COALESCE_TX_AGGR_MAX_FRAMES Maximum number of frames that can be aggregated into a block. ETHTOOL_A_COALESCE_TX_AGGR_TIME_USECS Time in usecs after the first packet arrival in an aggregated block for the block to be sent.
