Looks good overall, can we broaden the language a bit? Replace "a single Completion Queue Entry (CQE)" with "a single Completion Queue Entry (CQE) or descriptor write back"? I'm assuming your devices don't coalesce CQE writes. For non-RDMA devices the notion of CQE is a bit foreign but descriptor write back coalescing serves similar purpose. In either case host can't see the frame even if it's busy polling. So: Rx CQE coalescing allows multiple received packets to be coalesced into a single Completion Queue Entry (CQE) or descriptor writeback. ``ETHTOOL_A_COALESCE_RX_CQE_FRAMES`` describes the maximum number of frames that can be coalesced into a CQE or writeback. ``ETHTOOL_A_COALESCE_RX_CQE_NSECS`` describes max time in nanoseconds after the first packet arrival in a coalesced CQE to be sent.
