CVS commit: src/sys/net

Module Name:	src
Committed By:	yamaguchi
Date:		Tue Jul 28 07:01:23 UTC 2026

Modified Files:
	src/sys/net: if_spppsubr.c

Log Message:
sppp: use RUN_ONCE(9) to initialize keepalive related resources
to prevent panics during concurrent attach/detach

- Initialize keepalive resources (e.g. spppq_lock and keepalive_ch)
  once using RUN_ONCE(9) instead of the first attach.
- Do not free these resources on sppp_detach

NOTE:
We should release these resources in sppp_subr_modcmd(), but module
unloading/cleanup is not implemented yet.
