Merge branch 'add-ethtool-coalesce_rx_cqe_frames-nsecs-and-use-it-in-mana-driver'
Haiyang Zhang says:
====================
add ethtool COALESCE_RX_CQE_FRAMES/NSECS and use it in MANA driver
Add two parameters for drivers supporting Rx CQE Coalescing.
ETHTOOL_A_COALESCE_RX_CQE_FRAMES:
Maximum number of frames that can be coalesced into a CQE or
writeback.
ETHTOOL_A_COALESCE_RX_CQE_NSECS:
Max time in nanoseconds after the first packet arrival in a
coalesced CQE or writeback to be sent.
Also implement it in MANA driver with the new parameter and
counters.
