With pre-2.0.31-3, I'm experiencing a problem I haven't had since 22 May:
while using dialout PPP, the connection will occasionally stop passing
packets, and the syslog gets spammed with these messages:

Aug 6 05:42:30 topside kernel: ICMP redirect from 155.135.1.100

Aug 6 06:05:39 topside last message repeated 2 times

I don't receive these messages with recent 2.1 kernels, nor with Dave
Miller's pre-2.0.31-2. Here are the networking-related options I have for
the kernel:

CONFIG_INET=y
CONFIG_SYN_COOKIES=y
CONFIG_RST_COOKIES=y
CONFIG_NET_IPIP=m
CONFIG_IP_NOSR=y
CONFIG_NETDEVICES=y
CONFIG_PPP=y
CONFIG_NET_ETHERNET=y
CONFIG_NET_ISA=y
CONFIG_EEXPRESS=m
CONFIG_NE2000=m
