Remove the hidden include in flowtable.h as well and leave the two explicit #includes in ip_input.c and ip_output.c. 2009-06-06T17:01:44Z Robert Watson rwatson@FreeBSD.org 2009-06-06T17:01:44Z urn:sha1:d5fc25e5d6c52b306312784663ccad85923a9c76 require it. Submitted by: pjd 2009-03-19T01:43:03Z Bruce M Simpson bms@FreeBSD.org 2009-03-19T01:43:03Z urn:sha1:443fc3176dee8c923a5e1e465231de9dc4197489 This is purely a forwarding plane cleanup; no control plane code is involved. Summary: * Split IPv4 and IPv6 MROUTING support. The static compile-time kernel option remains the same, however, the modules may now be built for IPv4 and IPv6 separately as ip_mroute_mod and ip6_mroute_mod. * Clean up the IPv4 multicast forwarding code to use BSD queue and hash table constructs. Don't build our own timer abstractions when ratecheck() and timevalclear() etc will do. * Expose the multicast forwarding cache (MFC) and virtual interface table (VIF) as sysctls, to reduce netstat's dependence on libkvm for this information for running kernels. * bandwidth meters however still require libkvm. * Make the MFC hash table size a boot/load-time tunable ULONG, net.inet.ip.mfchashsize (defaults to 256). * Remove unused members from struct vif and struct mfc. * Kill RSVP support, as no current RSVP implementation uses it. These stubs could be moved to raw_ip.c. * Don't share locks or initialization between IPv4 and IPv6. * Don't use a static struct route_in6 in ip6_mroute.c. The v6 code is still using a cached struct route_in6, this is moved to mif6 for the time being. * More cleanup remains to be merged from ip_mroute.c to ip6_mroute.c. v4 path tested using ports/net/mcast-tools. v6 changes are mostly mechanical locking and *have not* been tested. As these changes partially break some kernel ABIs, they will not be MFCed. There is a lot more work to be done here. Reviewed by: Pavlin Radoslavov 2008-12-02T21:37:28Z Bjoern A.

This reduces the unneeded spamming of various headers into lots of files. For now, this leaves us with very few modules including vnet.h and thus needing to depend on opt_route.h.

Thus, such fake files won't be created at all if modules are built with the kernel. Some modules undergo cleanup like removing unused or unneeded options or .h files, without which they wouldn't build this way or the other.

Flow IDs and frag IDs are significantly less common in the IPv6 world (ie. rarely generated per-packet), so there should be smaller performance concerns. The sysctl defaults to 0 (sequential IP IDs).
