This is just a quick note to announce some cool new features to NetBSD's
networking code, recently introduced in NetBSD-current.
* Monotonically increasing "current time" timestamps have bee
added to the fast and slow timeout dispatch routines. These
can be used to implement network timers which compare "current
time" against "when timer will expire", which can can reduce
read/modify/write/compare/branch cycles to read/compare/branch,
or used for time-ordered timeout queues. TCP timers and the SYN
cache timers now use this PRT timer facility, which has resulted
in much less expensive timer expiration loops.

* Support for HIPPI, an 800Mbit/sec network technology, as been
added, along with a driver for the Essential Communications
RoadRunner HIPPI interface.
