Subject: [PATCH ethtool v3 0/7] pause frame stats

Hi!

Sorry about the delay from v2.


This set adds support for pause frame statistics.

First pause frame info is extended to support --json.

Pause stats are first of this kind of statistics so add
support for a new flag (--include-statistics).

Next add support for dumping policy to check if the statistics
flag is supported for a given subcommand.

Last but not least - display statistics.

v3:
 - rename the ctx variable to policy_ctx
 - instead of returning the flags policy save it to a member
   of struct nl_context, for potential reuse. Also we don't
   have to worry about returning flags and negative errors
   from the read helper this way :)

Jakub Kicinski (7):
  update UAPI header copies
  pause: add --json support
  separate FLAGS out in -h
  add support for stats in subcommands
  netlink: prepare for more per-op info
  netlink: use policy dumping to check if stats flag is supported
  pause: add support for dumping statistics
