use llt_fill_sa_entry() llt method to store lle address in sa.
* Eliminate L3_ADDR macro and either reference IPv4/IPv6 address
directly from lle or use newly-created llt_fill_sa_entry().
* Do not store sockaddr inside arp/ndp lle anymore.
and explicit calls to RTENTRY_FREE_LOCKED()
* Use lltable_prefix_free() in arp_ifscrub to be consistent with nd6.
* Rename <lltable_|llt>_delete function to _delete_addr() to note that
this function is used to external callers. Make this function maintain
its own locking.
* Use lookup/unlink/clear call chain from internal callers instead of
delete_addr.
* Fix LLE_DELETED flag handling
cleanup including unlinking/freeing
* Relax locking in lltable_prefix_free_af/lltable_free
* Do not pass @llt to lle free callback: it is always NULL now.
* Unify arptimer/nd6_llinfo_timer: explicitly unlock lle avoiding
unlock/lock sequinces
* Do not pass unlocked lle to nd6_ns_output(): add nd6_llinfo_get_holdsrc()
to retrieve preferred source address from lle hold queue and pass it
instead of lle.
* Finally, make nd6_create() create and return unlocked lle
* Separate defrtr handling code from nd6_free():
use nd6_check_del_defrtr() to check if we need to keep entry instead of
performing GC,
use nd6_check_recalc_defrtr() to perform actual recalc on lle removal.
* Move isRouter handling from nd6_cache_lladdr() to separate
nd6_check_router()
* Add initial code to maintain lle runtime flags in sync.
does actual new lle creation without extensive locking and existing
lle search.
Move lle updating code from gigantic in_arpinput() to arp_update_llle()
and some other functions.
IPv6 changes to follow.
use rwlock accessible via external functions
(IF_AFDATA_CFG_* -> if_afdata_cfg_*()) for all control plane tasks
use rmlock (IF_AFDATA_RUN_*) for fast-path lookups.

related cleanups:
- Require each driver to initalize a mutex in the scsi_low_softc that
is shared with the scsi_low code. This mutex is used for CAM SIMs,
timers, and interrupt handlers.
- Replace the osdep function switch with direct calls to the relevant
CAM functions and direct manipulation of timers via callout(9).
- Collapse the CAM-specific scsi_low_osdep_interface substructure
directly into scsi_low_softc.
- Use bus_*() instead of bus_space_*().
- Return BUS_PROBE_DEFAULT from probe routines instead of 0.
- No need to zero softcs.
- Pass 0ul and ~0ul instead of 0 and ~0 to bus_alloc_resource().
- Spell "dettach" as "detach".
- Remove unused 'dvname' variables.
- De-spl().
Tested by: no one
- Add a per-softc mutex as a driver lock.
- Use callout(9) instead of timeout(9).
- Set softc pointer in si_drv1 of cdev instead of looking softc
up via devclass in cdev methods.
Tested by: no one
- Don't recurse driver mutex.
- Don't hold driver mutex across fubyte/subyte.
- Replace fubyte/subyte loops with copyin/copyout calls.
- Use relatively sane locking in wl_ioctl().
- Use bus space accessors instead of in*()/out*().
- Use callout(9) instead of timeout(9).
- Stop watchdog timer in detach and don't hold mutex across
bus_teardown_intr().
- Use device_printf() and if_printf().
- De-spl().

Without this fix, the vnet was NULL and would crash.
This fix is similar to what was done inside the ioctl handler for PF.
Tested by:
(1) Boot a kernel with "options VIMAGE" enabled
(2) Type:
echo "map lo0 from 10.0.0.0/24 to ! 10.0.0.0/24 -> 127.0.0.1/32" > /etc/ipnat.rules ; service ipnat onerestart
