Yes, you now need to additionally put "options mii_bitbang" into your kernel configuration file if you don't use "options miibus" but "options mii" and individual PHY drivers in combination with one of the MAC drivers that where converted to use the common MII bitbang'ing code, see sys/conf/NOTES. Given that this is a rather exotic approach intended for embedded use it didn't occur to me to note it beyond NOTES. However, thinking about it I decided for stable/7 and stable/8 to automatically drag in the common MII bitbang'ing code if one of the MAC drivers depending on it is compiled into the kernel in order to not break POLA.
