We can't and don't plan to preserve the driver KPI for the 11 branch. We
actually plan to change it very much, in sake of keeping it stable there
on. Please see on what is going on in the projects/ifnet branch.

So, I'd suggest to introduce new 'struct ifmedia' with enough space,
and of course put extra space in there. Give a new value to SIOCGIFMEDIA.
Write a new clear code to handle it, without any extended bit tricks.

For the sake of userland API, save old current 'struct ifmedia' as
'struct oifmedia', and take old value of ioctl to OSIOCIGIFMEDIA.
Keep current code for old APU, only renaming the struct and ioctl
value.
