src/sys/arch/powerpc/booke/dev: pq3etsec.c
src/sys/dist/pf/net: pf.c pf_ioctl.c
src/sys/external/bsd/ipf/netinet: fil.c ip_fil_netbsd.c
src/sys/net: if_loop.c
src/sys/net/npf: npf_mbuf.c
src/sys/netinet: in.h in_offload.c in_offload.h ip_mroute.c ip_output.c
src/sys/netipsec: ipsec.c
Log Message:
Rename
ip_undefer_csum -> in_undefer_cksum
in_delayed_cksum -> in_undefer_cksum_tcpudp
The two previous names were inconsistent and misleading.
Put the two functions into in_offload.c. Add comments to explain what
we're doing.
The same could be done for IPv6.
