My apologies to Oliver - the changes he's referring to are the ones I submitted:
   https://www.spinics.net/lists/netdev/msg715248.html

which is related to this series:
   https://www.spinics.net/lists/netdev/msg714493.html

I wasn't aware of and didn't look for the series Oliver had previously
posted. *sigh*  I have been talking to Realtek about getting the issue
of RTL8156 spewing notifications every 32ms fixed (thinking a FW
change could fix it) for nearly three months.  It is unfortunate
timing that Roland Dreier decided to do something about it in December
- which I didn't expect to happen given this problem was reported
nearly two years ago.

Agreed. That's a two lines change to cdc_ether.c. I can submit this if
Oliver doesn't want to spin the series.

I've reviewed all three patches and besides one nit (which could be
ignored or fixed later), I'm offering my
   Reviewed-by: Grant Grundler <grundler@...omium.org>

in the off chance that helps get this accepted into net-next (and/or
5.11 RC release).

cheers,
grant
