Hello,

after I merged your patch and pushed to the server, I realized that you
forgot to update also the manual page (file ethtool.8.in). Please send
a follow-up patch with manual page update.

Thank you,
Michal

Hello,

Any news on this patch series?
Would someone have the time to take a look at it?

[PATCH ethtool-next 0/2] add support for PLCA RS

[Piergiorgio Beruto]

This patch adds support for the IEEE802.3cg-2019 Clause 148 PLCA
Reconciliation Sublayer. It adds get/set configuration and get status
functions. Additionally, shows PLCA capabilities and status when invoked
without arguments.

Piergiorgio Beruto (2):
  update UAPI header copies
  add support for IEEE 802.3cg-2019 Clause 148 - PLCA RS
