using ifp->if_addr_mtx:
- Initialize if_addr_mtx when ifnet is initialized.
- Destroy if_addr_mtx when ifnet is torn down.
- Rename ifmaof_ifpforaddr() to if_findmulti(); assert if_addr_mtx.
Staticize.
- Extract ifmultiaddr allocation and initialization into if_allocmulti();
accept a 'mflags' argument to indicate whether or not sleeping is
permitted. This centralizes error handling and address duplication.
- Extract ifmultiaddr tear-down and deallocation in if_freemulti().
- Re-structure if_addmulti() to hold if_addr_mtx around manipulation of
the ifnet multicast address list and reference count manipulation.
Make use of non-sleeping allocations. Annotate the fact that we only
generate routing socket events for explicit address addition, not
implicit link layer address addition.
- Re-structure if_delmulti() to hold if_addr_mtx around manipulation of
the ifnet multicast address list and reference count manipulation.
Annotate the lack of a routing socket event for implicit link layer
address removal.
- De-spl all and sundry.

ifp->if_resolvemulti(), do so with M_NOWAIT rather than M_WAITOK, so
that a mutex can be held over the call. In the FDDI code, add a
missing M_ZERO. Consumers are already aware that if_resolvemulti()
can fail.

lists. Add accessor macros.
This changes the size of struct ifnet, but ideally, all ifnet consumers
are now using if_alloc() to allocate these structures rather than
embedding them into device driver softc's, so this won't modify the
network device driver ABI.

extracted from tar archives. Otherwise, converting tar archives to
cpio format (with "bsdtar -cf out.cpio @in.tar") convert every entry
into a hard link to a single file. This simple logic breaks hard
links, but that's better than the alternative.

that knows how to extract UMA(9) allocator statistics from a core dump or
live memory image using kvm(3). The caller is expected to provide the
necessary kvm_t handle, which is then used by libmemstat(3).
With these changes, it is trivially straight forward to re-introduce
vmstat -z support on core dumps, which was lost when UMA was introduced.
In the short term, this requires including vm/ include files that are not
intended for extra-kernel use, requiring in turn some ugliness.
- Conforming to the latest ether_ifattach() change;
- Moving PCCARD_API_LEVEL to the right place.
