Big patches are fun.
These two attached patches also roll in a switch to MAC_FMT and MAC_ARG, and
use IEEE80211_DATA_LEN when possible. Otherwise, it's the same as before
except split into two patches.

Hello!
gregkh-driver-network-class_device-to-device.patch, which briefly
appeared in Linux 2.6.18-rc1-mm1 broke MadWifi, which is copying the
physical device information from the master network device to the
virtual network devices:
SET_NETDEV_DEV(dev, mdev->class_dev.dev);
The same code exists
