from the forwarding table's users:
Introduce rt_walktree() for walking the routing table and
applying a function to each rtentry. Replace most
rn_walktree() calls with it.
Use rt_getkey()/rt_setkey() to get/set a route's destination.
Keep a pointer to the sockaddr key in the rtentry, so that
rtentry users do not have to grovel in the radix_node for
the key.
Add a RTM_GET method to rtrequest. Use that instead of
radix_node lookups in, e.g., carp(4).
Add sys/net/link_proto.c, which supplies sockaddr routines for
link-layer socket addresses (sockaddr_dl).
Cosmetic:
Constify. KNF. Stop open-coding LIST_FOREACH, TAILQ_FOREACH,
et cetera. Use NULL instead of 0 for null pointers. Use
__arraycount(). Reduce gratuitous parenthesization.
Stop using variadic arguments for rip6_output(), it is
unnecessary.
Remove the unnecessary rtentry member rt_genmask and the
code to maintain it, since nothing actually used it.
Make rt_maskedcopy() easier to read by using meaningful variable
names.
Extract a subroutine intern_netmask() for looking up a netmask in
the masks table.
Start converting backslash-ridden IPv6 macros in
sys/netinet6/in6_var.h into inline subroutines that one
can read without special eyeglasses.
One functional change: when the kernel serves an RTM_GET, RTM_LOCK,
or RTM_CHANGE request, it applies the netmask (if supplied) to a
destination before searching for it in the forwarding table.
I have changed sys/netinet/ip_carp.c, carp_setroute(), to remove
the unlawful radix_node knowledge.
Apart from the changes to carp(4), netiso, ATM, and strip(4), I
have run the changes on three nodes in my wireless routing testbed,
which involves IPv4 + IPv6 dynamic routing acrobatics, and it's
working beautifully so far.

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.
lpt at jensenio doesn't seem to have a specific interrupt vector
but uses a normal EISA interrupt.
Fixes another part of PR port-alpha/36628 and PR port-alpha/20386.
- Replace DQ_LOCK/DQ_WANT/sleep/wakeup with a mutex `dq_interlock'. Use this
mutex to protect all quota values and flags.
- Protect the hashtable with a mutex.
- Never update quotas for the quota files on the same file system. Prevents
a deadlock when dqsync() has to change the quota file's size (PR #13942).

While here, remove some dead code I added when I ported the code from OpenBSD.
IMPORTANT : You must download the 2.14.4 firmware or update your

working.
If interrupts are enabled when kernel is switched to lwp_trampoline(),
we could get lock errors by interrupts before lwp_unlock() in lwp_startup()
is called. The spl is lowered by spl0() in lwp_startup() after lwp_unlock().
