Yes, and this (from sys/netinet/tcp_var.h):
#define TCP_RTTVAR_SCALE 16 /* multiplier for rttvar; 2 bits */
#define TCP_RTTVAR_SHIFT 4/* shift for rttvar; 2 bits */
...should say "...for rttvar; 4 bits frac." in both places.

Hi everybody,
just a nit in sys/netinet/tcp_input.c:tcp_xmit_timer(). A comment says:
/*
