f6030d6ac1
- Based on lessons learnt with dc(4) (see r185750), add bus space barriers to
the MII bitbang read and write functions as well as to instances of page
switching.
- Add missing locking to ed_ifmedia_{upd,sts}().
- Canonicalize some messages.
- Based on actual functionality, ED_TC5299J_MII_DIROUT should be rather named
ED_TC5299J_MII_DIRIN.
- Remove unused headers.
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.
