KVI
>Environment:
FreeBSD kvip55.lan 5.3-BETA7 FreeBSD 5.3-BETA7 #1: Sat Oct 2 20:36:16 CEST 2004 root@kvip88.kvi.nl:/usr/obj/usr/src/sys/KVIP88 i386
>Description:
Turning on altq filtering using for example following 2 lines in pf.conf:
altq on bfe0 priq bandwidth 350Kb queue {q}
queue q priority 1 priq(default)
and doing some upload from the pc results in the outgoing traffic limited by approx 160-170Kbit/s:
$ pfctl -vvsq
queue q priq( default )
[ pkts: 6515 bytes: 7183041 dropped pkts: 0 bytes: 0 ]
[ qlength: 4/ 50 ]
[ measured: 18.2 packets/s, 162.56Kb/s ]
The same pf.conf was checked on 2 other systems: OpenBSD-current on the same hardware and 5.3-BETA7 on different machine with very close configuration. In both cases the problem is not reproduced.
>How-To-Repeat:
Find Broadcom 4401 network card and turn on queueing on it.
>Fix:
None.
