Subject: [BUG] net: stmmac: socfpga ethernet no longer working on linux-next

Hi,

The stmmac ethernet has stopped working in linux-next and linus/master
branch(v4.17-11782-gbe779f03d563)

It appears that the stmmac ethernet has stopped working after these 2 commits:

4dbbe8dde848 net: stmmac: Add support for U32 TC filter using Flexible RX Parser
5f0456b43140 net: stmmac: Implement logic to automatically select HW Interface

If I move to this commit "565020aaeebf net: stmmac: Disable ACS
Feature for GMAC >= 4", then the stmmac works again on SoCFPGA.

I was following this thread:
https://www.spinics.net/lists/netdev/msg502858.html

Was wondering if there was a patch to fix dwmac-sun8i that the socfpga
platform needs as well?

Thanks,
Dinh
