Red Hat Bugzilla – Bug 149589
CAN-2005-0209 netfilter SKB problem

"If we forward a fragmented packet, we can have ip_summed set to
CHECKSUM_HW or similar. This is fine for local protocol processing,
but once if we are forwarding this packet we want to reset ip_summed
to CHECKSUM_NONE." This allows you to crash a host remotely using bad
fragments but only affects certain NICs. Dave Miller said "Acenic and
SunGEM are the only two cards affected which are in widespread use."
