It is set to the default 0.1s per IEEE 1394 in core-card.c::fw_card_initialize.

If card->split_timeout_jiffies or card->split_timeout_cycles /ever/ become
zero, then only due to a memory corrupting bug.

OK, I'll send a stricter version of "firewire: net: throttle TX queue before
running out of tlabels".
