Mbuf networking issue

[Steven King]

Hi all,

I have been tracking down a problem related to memory corruption of part of
the mbuf structures during a heavy network load.  It ends up attempting to
load an invalid address into a register causing a program exception
(powerpc).

Looking through the BSD glue code, we noticed that splimp(), splnet() and
splx() do nothing, does this mean there is no protection on the mbufs used
by the stack? Should these be defined?

Thanks,
