- MP-safe drivers provide a mutex to ifmedia that is used to serialize access to media-related structures / hardware regsiters. Converted drivers use the new ifmedia_init_with_lock() function for this. The new name is provided to ease the transition. - Un-converted drivers continue to call ifmedia_init(), which will supply a compatibility lock to be used instead. Several media-related entry points must be aware of this compatibility lock, and are able to acquire it recursively a limited number of times, if needed. This is a SPIN mutex with priority IPL_NET. - This same lock is used to serialize access to PHY registers and other MII-related data structures. The PHY drivers are modified to acquire and release the lock, as needed, and assert the lock is held as a diagnostic aid. The "usbnet" framework has had an overhaul of its internal locking protocols to fit in with the media / mii changes, and the drivers adapted. USB wifi drivers have been changed to provide their own adaptive mutex to the ifmedia later via a new ieee80211_media_init_with_lock() function. This is required because the USB drivers need an adaptive mutex. Besised "usbnet", a few other drivers are converted: vmx, wm, ixgbe / ixv. mcx also now calls ifmedia_init_with_lock() because it needs to also use an adaptive mutex. The mcx driver still needs to be fully converted to NET_MPSAFE.
