213eac1f2c Add new tunable 'net.link.ifqmaxlen' to set default send interface
queue length. The default value for this parameter is 50, which is
quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only
sysctl with the same name, so that it's possible to retrieve the
current value.

be5740a255 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.

307f54dd3d Add preliminary support for the OLICOM OC2231 and OC2232. This is the
first driver that does the configuration dance with CFE's.  There's
likely some additional configuration that's needed to get things
working completely...

8c6bf65efb Some PC Card variants of the 82365 don't seem to like setting the IRQ
number in the irq register.  While there are other issues with these
variants, avoiding writing to it helps interrupt generation on at
least one card, and doesn't hurt on the others.  Flag ISA attachment
as needing INT_NO_REG written, and don't update the PC Card attachment
(which will have the effect of not touching it for PC Cards).

Document this in a comment, and tweak one or two formatting nits while
I'm here.

b3ec9d20e2 Make ex(4) MPSAFE:
- Add a mutex to the softc to protect the softc and device hardware.
- Use a private watchdog timer.
- Setup interrupt handler after ether_ifattach().
- Use bus_foo() rather than bus_space_foo() and remove bus space tag and
  handle from softc.

f70f525b49 - 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",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.

4ddf28af87 Add the olicom OC2231 and OC2232 to the list of cards that we should

5d770a09e8 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.

567ba9b00a 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.

037ce3f3f4 Since if_ex doesn't contain locking or run with INTR_MPSAFE, mark
the interface as IFF_NEEDSGIANT so if_start is run holding Giant.

Note: there are locking macros in if_exreg.h, but they appear to be
unused.

7d7307d2e1 Remove improper use of if_addrhead in device drivers to check
if the link-level address has been initialized already.

The majority of modern drivers never does this and works fine, which
makes me think that the check is totally unnecessary and a residue
of cut&paste from other drivers.

This change is done to simplify locking because now almost none of the
drivers uses this field. The exceptions are "ct" "ctau" and "cx"
where i am not sure if i can remove that part.
