parentgenetlink: Fix generic netlink family unregister (diff)
firewire: net: really fix maximum possible MTU
The maximum unicast datagram size /without/ link fragmentation is 4096 - 4 = 4092 (max IEEE 1394 async payload size at >= S800 bus speed, minus unfragmented encapssulation header). Max broadcast datagram size without fragmentation is 8 bytes less than that (due to GASP header). The maximum datagram size /with/ link fragmentation is 0xfff = 4095 for unicast and broadcast. This is because the RFC 2734 fragment encapsulation header field for datagram size is only 12 bits wide.
