Log message:
Permit the stack to check transport and network checksums. Although the link
provides stronger integrity checks, it needn't cover the end-to-end transport
path. And it is in any case a layer violation for one layer to disable the
checks of another. Skipping the network check saved ~2.4% +/- ~0.2% of cp_time
(sys+intr) on the forwarding path of a 1Ghz AMD G-T40N (apu1). Other checksum
speedups exist which do not skip the check.
