This will introduce crashes because you only added the adjust_link
method to one of the two stmmac_ops instances in
drivers/net/ethernet/stmicro/stmmac/dwmac4_core.c

Furthermore, a patch series should always have a header posting
with subject of the format "[PATCH 0/N]: xxx" which describes at
a high level what the patch series does as a whole, how it is doing
it, and why it is doing it that way.

Thank you.
