it is not normal path
this string is used to calculate number of symbols in "net/%s/neigh/%s" used below

Then probably better would be to add +1 rather than
use a rather odd filename.

Hi, Joe
	I use the splicing method to rewrite it in patch V2 [0001-neigh-Adjustment-calculation-method-of-neighbour-pat.patch], I think it will be clearer. Looking forward to your reply.
Thanks, best wish to you.
