net: dsa: sja1105: Reject unsupported link modes for AN
Ethernet flow control: The switch MAC does not consume, nor does it emit pause frames. It simply forwards them as any other Ethernet frame (and since the DMAC is, per IEEE spec, 01-80-C2-00-00-01, it means they are filtered as link-local traffic and forwarded to the CPU, which can't do anything useful with them). Duplex: There is no duplex setting in the SJA1105 MAC. It is known to forward traffic at line rate on the same port in both directions. Therefore it must be that it only supports full duplex.
