apply the following patch, please. It seems that in syncppp.c
remained the two skb->priority=1 statements from the Linux 2.0 version.
In 2.2 it causes the keepalive packet to be sent with _lower_ priority
than other packets, which is a Bad Thing(tm) - it causes that kernel
thinks the line is down when there is traffic high enough to delay
or drop MAXALIVECNT or more keepalive packets. With this patch,
keepalive packets are delivered in the normal order and it seems to
improve the syncppp.c behaviour on highly loaded lines.
Thanks,
