[PATCH net-next v6 0/2] net: ethtool: Introduce ethnl dump helpers

[Maxime Chevallier]

Hi everyone,

This is V6 for per-phy DUMP helpers, that includes even more
simplification, as this now boils down to 2 patches :
 - The first one introduce per-phy ->start(), ->dumpit() and ->done()
   helpers and uses them for plca and pse-pd
 - The second patch converts the net/ethtool/phy.c code, to avoid
   open-coding the DUMP operation.

Thanks,

Maxime

Changes in V6:
 - Squash pse and plca patches into the first one, to avoid unused
   functions (Jakub)

Changes in V5:
 - Move to a less generic approach, focusing only on the PHY case.

Changes in V4:
 - Don't grab rcu_read_lock when we already have a refcounter netdev on
   the filtered dump path (Paolo)
 - Move the dump_all stuff in a dedicated helper (Paolo)
 - Added patch 1 to set the dev in ctx->req_info

Changes in V3:
 - Fixed some typos and xmas tree issues
 - Added a missing check for EOPNOTSUPP in patch 1
 - Added missing kdoc
 - Added missing comments in phy_reply_size

Changes in V2:
 - Rebased on the netdev_lock work by Stanislav and the fixes from Eric
 - Fixed a bissectability issue
 - Fixed kdoc for the new ethnl ops and fields
