hmm, in linux-3.2 (and older), linux/mii.h doesn't include anything else.
seems linux-3.3-rc1 has started including linux/ethtool.h too. however, that
is unnecessary for userspace, so i'll probably send a patch to move the
include to __KERNEL__.
dv-eth_phy.c has some hacks in it to make it build with even older kernel
headers. maybe i should have it just not build that driver on older systems
rather than try to support it ...
