Hello
I have experienced dst cache overflow errors with three FC3 firewalls under
medium load.
It seems that the cache leak is now found
(http://oss.sgi.com/archives/netdev/2005-01/msg01367.html) and there is a fix
for that:

to->priority = from->priority;
to->protocol = from->protocol;

I think that vanilla kernel 2.6.11 contains this fix, but does any FC-kernels
have this fix included? If not, does anybody know is this fix going to be
included to the new FC-kernels?
