Well, we could split out those we know are likely to get tested.  I
have a number of boards with Marvell devices i can test. Florian has
Broadcom boards. I also have a couple of boards with Micrel KSZ8041,
which would be interesting because they are Fast Ethernet. Bootlin can
test some of the mscc PHYs.

We also might want to get some targeted testing. The microchip_t1.c
could be interesting, since it is a T1 device. There was another T1
added in the last year, but i forget which.

Just doing this testing might give us an idea if we really should
expect problems.
