Shaun Ruffell 89ea0430df dahdi_dynamic_eth: Make ztdeth_exit() symetrical with ztdeth_init() and fix race on unload. ... Minor change to follow generally recommended practice. Prevents new packets from being queued up for devices when they are about to be cleaned up. Also clean up any skbs that may still be on the queue after unloading. Also closes anoter potential kernel oops on module unload. It was possible to delete the private structure while the master span process was running. The result was an attempt to page memory from interrupt context. Make sure that the pvt function is set and cleared under the zlock. Also do not assume that the pvt pointer is valid in ztdeth_transmit.
