Port some parts of the stmmac selftest to the FEC. This patch was tested
on iMX6DL.
With this tests it is possible to detect some basic issues like:
- MAC loopback fail: most probably wrong clock configuration.
- PHY loopback fail: incorrect RGMII timings, damaged traces, etc

Hi

Oleksij

I've not done a side-by-side diff with stmmac, but i guess a lot of
this code is identical?

ack

Rather than make a copy/paste, could you move
it somewhere under net and turn it into a library any driver can use?

yes, I assume, it is possible to make this code complete generic for all
devices, but we will need to provide some more call backs. For example
enable MAC loop back, enable DSA loopbacks and so on.

Do you have ideas for the new location of generic selftest code and
where  can be added loopback options for different levels?

Regards,
Oleksij
