[PATCH] remote memory corruptor in ibmtr.c
ip_summed changes last summer had missed that one. As the result,
we have ip_summed interpreted as CHECKSUM_PARTIAL now. IOW,
->csum is interpreted as offset of checksum in the packet. net/core/*
will both read and modify the value as that offset, with obvious
reasons. At the very least it's a remote memory corruptor.
