I've recently setup a box with a PCA-200E using HARP.

I am having a packet loss / out of sequence issue:

100 packets transmitted, 96 packets received, 4% packet loss
round-trip min/avg/max/stddev = 1.504/4.713/67.068/12.492 ms

(this is across the ATM to the other side).

Also, some interesting out of sequence issues, probably due to the delay
of said packet:

136 bytes from 209.123.37.30: icmp_seq=75 ttl=64 time=1.599 ms
136 bytes from 209.123.37.30: icmp_seq=77 ttl=64 time=1.606 ms
136 bytes from 209.123.37.30: icmp_seq=78 ttl=64 time=1.553 ms
136 bytes from 209.123.37.30: icmp_seq=76 ttl=64 time=56.113 ms
136 bytes from 209.123.37.30: icmp_seq=79 ttl=64 time=1.577 ms
136 bytes from 209.123.37.30: icmp_seq=80 ttl=64 time=1.512 ms

I've read about the patch, but from what I can tell, it already exists on
this machine (it is a fresh install of 4.4 RELEASE).

FreeBSD aggr1.oct.dcjn.net 4.4-RELEASE FreeBSD 4.4-RELEASE #1: Wed Dec 12 20:22:47 EST 2001
root@aggr1.oct.dcjn.net:/usr/src/sys/compile/PCROUTER  i386

Am I missing something obvious? We're only passing about 4 mb/s over this
interface, doesn't seem that it should do this.

Any pointers would be greatly appreciated.
