SubjectRE: [PATCH] net: stmmac: Read user ID muliple times if needed.
Date
We assert / de-assert the reset line, but the CPU is too fast and the IP is still 
in reset when we later try to read user ID / Synopsys ID. Another option would
be to add a delay after we reset.

We shouldn't even try to read it if IP is in reset ...
