[PATCH net-next 0/4] net: phy: mscc-miim: reduce waiting time between MDIO transactions

Hello,

This series aims at reducing the waiting time between MDIO transactions
when using the MSCC MIIM MDIO controller.

I'm not sure we need patch 4/4 and we could reasonably drop it from the
series. I'm including the patch as it could help to ensure the system
is functional with a non optimal configuration.

We needed to improve the driver's performances as when using a PHY
requiring lots of registers accesses (such as the VSC85xx family),
delays would add up and ended up to be quite large which would cause
issues such as: a slow initialization of the PHY, and issues when using
timestamping operations (this feature will be sent quite soon to the
mailing lists).

Thanks,
Antoine
