> This patchset fixes an issue with the OdroidC2 board (DWMAC + RTL8211F).
> The platform seems to enter LPI on the Rx path too often while performing
> relatively high TX transfer. This eventually break the link (both Tx and
> Rx), and require to bring the interface down and up again to get the Rx
> path working again.
>
> The root cause of this issue is not fully understood yet but disabling EEE
> advertisement on the PHY prevent this feature to be negotiated.
> With this change, the link is stable and reliable, with the expected
> throughput performance.
>
> The patchset adds options in the generic phy driver to disable EEE
> advertisement, through device tree. The way it is done is very similar
> to the handling of the max-speed property.
Patches 1-3 applied to net-next, thanks.
