This breaks NFS boot on the Raspberry Pi 3+, the same issue appears in
5.15.  We don't appear to get any incoming traffic:

  Begin: Waiting up to 180 secs for any network device to become available ... done.

There was a similar issue in mainline last release, I can't remember the
exact fix though.

A bisect identifies "net: phy: microchip: force IRQ polling mode for
lan88xx" as the problematic commit.
