- Add a lot of missing selinit() and seldestroy() calls.
- Merge selwakeup() and selnotify() calls into a single selnotify().
- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.
Note: please pass appropriate value of 'events' where possible.

to _ro_rt. Use rtcache_getrt() to access a route cache's struct
rtentry *.
Introduce struct ifnet->if_dl that always points at the interface
identifier/link-layer address. Make code that treated the first
ifaddr on struct ifnet->if_addrlist as the interface address use
if_dl, instead.
Remove stale debugging code from net/route.c. Move the rtflush()
code into rtcache_clear() and delete rtflush(). Delete rtalloc(),
because nothing uses it any more.
Make ND6_HINT an inline, lowercase subroutine, nd6_hint.
I've done my best to convert IP Filter, the ISO stack, and the
AppleTalk stack to rtcache_getrt(). They compile, but I have not
tested them. I have given the changes to PF, GRE, IPv4 and IPv6
stacks a lot of exercise.
If you use a route-to rule such as 'pass out quick on ath0 route-to
gre2 all', and the MTU on gre2 is smaller than the MTU on ath0,
then pf_route() will fragment your packet by calling ip_fragment().
Because pf_route() did not set M_CSUM_IPv4, ip_fragment() would
not compute the checksum on the fragments, and PF would send IP
fragments with bad checksums out of gre2.
The mbuf chain wasn't being walked and thus fin_m was not updated to point
to the new first mbuf with data in it.
Patch from the official IPFilter repository.
alignment and nothing guarantees that IPv6 packets in mbufs are 8-byte
aligned. gcc was coalescing adjacent 32-bit compares into "ldx" on
sparc64, leading to alignment faults when processing icmp6 arriving on
gif with IPv4 outer addresses.
Fix mostly from darrenr@. Discussed extensively on port-sparc64.
set to rn_walktree.
Introduce rt_walktree(), which applies a subroutine to every route
in a particular address family. Use it instead of rn_walktree()
virtually everywhere. This helps to hide the routing table
implementation.
update in ICMP error messages. In the test case for this, the wrong
input was actually being used (it should be the headers from the previous
packet output) and therefore the expected results were also wildly wrong.
