The XGMAC ECC Safety code has likely been just copied from the DW GMAC
v5 (DW QoS Eth) part. So this change is partly relevant to that code too. I
can't confirm that the special errors support is relevant to the DW
QoS Eth too (it likely is though), so what about splitting this patch
up into two:
1. Elaborate the errors description for DW GMAC v5 and DW XGMAC.
2. Add new ECC safety errors support.
?
On the other hand if we were sure that both DW QoS Eth and XGMAC
safety features implementation match the ideal solution would be to
refactor out the common code into a dedicated module.
