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.
