c47476d7e6 Migrate many bus_alloc_resource() calls to bus_alloc_resource_anywhere().
Most calls to bus_alloc_resource() use "anywhere" as the range, with a given
count.  Migrate these to use the new bus_alloc_resource_anywhere() API.

2dd1bdf183 Convert rman to use rman_res_t instead of u_long
Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources.  For
now, this is still compatible with u_long.

This is step one in migrating rman to use uintmax_t for resources instead of
u_long.

Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.

This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

2a8c860fe3 In order to reduce use of M_EXT outside of the mbuf allocator and
socket-buffer implementations, introduce a return value for MCLGET()
(and m_cljget() that underlies it) to allow the caller to avoid testing
M_EXT itself.  Update all callers to use the return value.

With this change, very few network device drivers remain aware of
M_EXT; the primary exceptions lie in mbuf-chain pretty printers for
debugging, and in a few cases, custom mbuf and cluster allocation
implementations.

NB: This is a difficult-to-test change as it touches many drivers for
which I don't have physical devices.  Instead we've gone for intensive
review, but further post-commit review would definitely be appreciated
to spot errors where changes could not easily be made mechanically,
but were largely mechanical in nature.

eb956cd041 Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

d557a26b80 Generalize the workaround for the Hitachi HT-4840-11. The Contec
C-NET(PC) has a cfe at location 1 that has both an odd irq mask (it
matches pc98 machines, so maybe it was a flag for pc98 operation) as
well as a memory map.  Since this driver doesn't know how to cope, we
start with cfe2, which is purely an I/O space mapped and that seems to
make it work.  I say 'seems' here, because the card I have doesn't
seem to have the right dongle for full testing...

a43561c252 - Use bus_foo() rather than bus_space_foo() and retire the bus tag and handle
from the softc.
- Rework the watchdog timer to match other NIC drivers:
  - Start a timer in fe_init() that runs once a second and checks a counter
    in the softc that is identical to the deprecated 'if_timer'.
  - Just adjust the softc tx timeout value when sending packets instead of
    scheduling the timer.
- Use IFQ_SET_MAXLEN().

4a0d6638b3 - Store pointer to the link-level address right in "struct ifnet"
rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",

  to use IF_LLADDR() instead.

2a0146bdf1 Preliminary support for Xircom Credit Card Adapter. Not to be
confused with the Credit Card Adapter II and its spawn (which the xe
driver supports).  These changes get my card probing and attaching.  I
recently won one of these (and a NEC rebadged version) in an lot
auction.  The NEC didn't work, so I took it apart and found the
MB86960A chip and then modified if_fe_pccard.c to attach.  I can't
test this card further since I have no dongle for this card.

ad4f426ef6 Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash.  Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

327f4aba35 we don't need the offset in the attr memory to get the ethernet
address, nor do we need the alignment requirements, so eliminate them.
This likely means that we can now collapse some of the entries as we
have no need of them anymore (they match other entries and were there
only to get the right attr memory offset of the enet addr).

3b36b3703e Rework pccard attachment a little. Now both of my fe based ethernet
cards work.  These changes depend on the expanded funce parsing that
just was committed to pccard_cis.c.  In NetBSD the ethernet address
was read out of attr memory directly.  We rely on the kernel pccard
parser to pulll this information out of what appears to be an obsolete
funce with the information in it.
