I'm currently using cnmac0 on ukphy0 and I'm wondering if I should be
using cnmac2/3 on brgphy0/1 .
Any thoughts? I know cnmac0/1 are Cu only, whereas cnmac2/3 could be
SFP if the switch they were connected on could be manipulated. I have
contacts at Cavium, but last time I asked about the internal switch on
an ARM64 box we use they would only release info under NDA. :-(
