Hi,

This is an early RFC which adds the XPCS and ETHQOS plumbing required
to enable 10 Gigabit Ethernet on the Qualcomm Nord SoC. This is the
first time USXGMII together with an external PCS is being supported by
the dwmac-qcom-ethqos driver.

There are currently 3 in-flight series that adds glues to DW XPCS and stmmac: 

This one,
The Rockchip one from Coia [1]
The S32 one from Jan [2]

It would nice if some of you could help maintain the core XPCS driver, and make sure
these series aren't stepping on one another :( I personnaly don't have any XPCS HW
for tests.

You don't have to do it alone, multiple people can co-maintain that :) Maybe
Synopsys folks can also chime in ?

Thank you for sharing these series, I can help review them based on my
understanding of this IP. Hope that helps.
