* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".
sync with more-recent LBL 0.4, about loopback interface detection
(/^lo[0-9]?$/).
CAVEAT: with GENERIC kernel on laptops laptops, pcap_lookupdev would almost
always pick eon0 as the interface, and fails because eon0 has no bpf
attachment. we may want to change pcap_lookup{,dev} to check if the
interface has bpf attachment or not.
almost in sync with tcpdump.org source code tree.
"tcp" will match both IPv4 TCP and IPv6 TCP.
"ip6" will match IPv6.
you can chase header chain by using "protochain" instead of "proto"
(but bpf code is not optimizable in this case)
commit to tcpdump will follow.
I've sent this fix to LBL guys to get no response. I wonder why it was.
