[PATCH net-next v6 0/3] add ethtool COALESCE_RX_CQE_FRAMES/NSECS and use it in MANA driver

[Haiyang Zhang <haiyangz@linux.microsoft.com>]

From: Haiyang Zhang <haiyangz@microsoft.com>

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.

  net: ethtool: add ethtool COALESCE_RX_CQE_FRAMES/NSECS
  net: mana: Add support for RX CQE Coalescing
