From Alan Carvalho de Assis (2015-05-30). + * net/net_initialize.c, net/detdev, and net/socket: The network device + list was protected by a re-entrant semaphore. With the recent change + to support network device callback, the network stack needs to access + the network device list too. Some drivers, however, run the network + stack from the interrupt level -- this is bad but a fact in the + current state. Of course, those drivers are unable to take the + semaphore and would assert. + The solution here is to eliminate the device devices semaphore + altogether. This eliminates netdev_semtake() and netdev_semgive() + and replace them with net_lock() and net_unlock() which have the + larger scope that is needed and will integrate properly with the + dinosaur interrupt driven stack (2015-05-31).
