Subject: [PATCH v3 ethtool 0/4] MAC Merge layer support

Add support for the following 2 new commands:

$ ethtool [ --include-statistics ] --show-mm <eth>
$ ethtool --set-mm <eth> [ ... ]

as well as for:

$ ethtool --include-statistics --show-pause <eth> --src pmac|emac|aggregate
$ ethtool --include-statistics --show-pause <eth> --src pmac|emac|aggregate
$ ethtool -S <eth> --groups eth-mac eth-phy eth-ctrl rmon -- --src pmac

and some modest amount of documentation (the bulk of it is already
distributed with the kernel's ethtool netlink rst).

This patch set applies on top of "[v5,ethtool-next,1/1] add support for
IEEE 802.3cg-2019 Clause 148", because otherwise it would conflict with it:

I believe Michal hasn't gotten to it yet, but I'm putting Piergiorgio on
CC too, in case there are other reasons why I shouldn't wait for his patch
to be merged first.

Vladimir Oltean (4):
  netlink: add support for MAC Merge layer
  netlink: pass the source of statistics for pause stats
  netlink: pass the source of statistics for port stats
  ethtool.8: update documentation with MAC Merge related bits
