[PATCH net-next] firewire: net: really fix maximum possible MTU

2016-10-29 Thread Stefan Richter
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 datagr
