I saw.

Yeah, TQ not TO.  Both look similar with squiggles
underneath them when using spell checking.

It's a #define, all the others are fixed strings.

Anyway, using
	seq_printf(seq, "  Originator      last-seen (#/%d)           Nexthop [outgoingIF]:   Potential nexthops ...\n",
		   BATADV_TQ_MAX_VALUE);
is probably trivially smaller overall code size too.

Your code, you decide...

cheers, Joe
