Modified files:
sys/kern uipc_socket.c
sys/netinet ip_input.c udp_usrreq.c
sys/sys socket.h
Log:
Introduce the SO_BINTIME option which takes a high-resolution timestamp
at packet arrival.
For benchmarking purposes SO_BINTIME is preferable to SO_TIMEVAL
since it has higher resolution and lower overhead. Simultaneous
use of the two options is possible and they will return consistent
timestamps.
This introduces an extra test and a function call for SO_TIMEVAL, but I have
not been able to measure that.
