Re: [PATCH 07/14] net: axienet: Fix SGMII support

Phylink currently expects the result of the in-band negotiation at
the MAC PCS to be propagated to the MAC by hardware (as this is what
happens with mvneta and mvpp2, the first two MACs that phylink
supports.)  If there is hardware that requires something else, then
that will need to be revisited, and will result in not only code but
also documentation updates as well.
Hi Russell

This is an issue i'm having at the moment with Marvell switches. They
do not propagate the results to the MAC. So when i get an interrupt
from the SERDES that the link is up, i'm programming the MAC as
needed.
