Subject: [PATCH v2 ethtool 0/5] 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 the PLCA UAPI update:
https://patchwork.kernel.org/project/netdevbpf/cover/cover.1673458497.git.piergiorgio.beruto@gmail.com/

Vladimir Oltean (5):
  uapi: add kernel headers for MAC merge layer
  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
