[V2,net-next,00/11] net: hns3: updates for -next

Message

There are several updates relating to the interrupt coalesce for
the HNS3 ethernet driver.

#1 adds support for QL(quantity limiting, interrupt coalesce
   based on the frame quantity).
#2 queries the maximum value of GL from the firmware instead of
   a fixed value in code.
#3 adds support for 1us unit GL(gap limiting, interrupt coalesce
   based on the gap time).
#4 renames gl_adapt_enable in struct hns3_enet_coalesce to fit
   its new usage.
#5 & #6 adds support for the dynamic interrupt moderation,
   and adds a control private flag in ethtool.
#7 adds wrapper function for state initialization.
#8 adds a check for the read-only private flag.
#9 & #10 adds support for EQ/CQ configuration, and adds a control
   private flag in ethtool.
#11 adds debugfs support for interrupt coalesce.

change log:
V2 - reorder #2 & #3 to fix compiler error.
     fix some checkpatch warnings in #10 & #11.
