freebsd stable - Apr 2004 - Per-interface polling(4) controls

Dear -STABLE users,

I've backported my patches that implement per-interface polling(4)
controls.  The RELENG_4 patchset for testing is available here:

	http://people.FreeBSD.org/~ru/patches/polling.patch

The patchset also includes an updated vr(4) driver with polling(4)
support.


Cheers,

Yay!  I was able to build and boot a system using this patch, giving the 
following "ifconfig -m" output:

Note that the second interface (sis0) isn't connected at the moment--
I'd
havta swap some cables around (2nd NIC I mainly use for testing).  But I was 
able to beat on the fxp0 interface for a while and things look good:

28-sec# ping -f -s 1000 prime
PING prime.local (192.168.1.3): 1000 data bytes
.^.
--- prime.local ping statistics ---
58200 packets transmitted, 58199 packets received, 0% packet loss
round-trip min/avg/max/stddev = 0.434/0.462/6.063/0.143 ms
