I am experiencing this oops too. And with a size of around 5000 I get about
50% packet loss.
Doing a ping xxx.xxx.xxx.xxx -s 20000 from a host through the bridge to
another host also oopses the bridge box.
Lennert:
in net/ipv4/netfilter/ip_conntrack_standalone.c the function ip_refrag() is
registered onto NF_IP_POST_ROUTING with priority NF_IP_PRI_LAST.
So: this function will try to fragment stuff on the bridge POST_ROUTING
hook. Is this healthy?
Unfortunately I don't know enough of the bridge code and ip code to know
this for sure.
Also: is it healthy that connection tracking defragments the ip packets on
the bridge PREROUTING hook? Doesn't this give problems if the bridge/router
box has to bridge those frames (instead of route them)?

cheers,
Bart
