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.

as being supported, but in reality it isn't. The EM1144-T,
{XJ,CC}{3288,3336} have the SMC chips in them, but aren't conformant MFC
cards, so they need their own driver.
Also, it does little harm to list the 8020BT, so remove #if 0.

Move ethernet MAC address setting into pccard attachment
Fix panic from IFP2ENADDR() use prior to if_alloc
Remove OLDCARD compat support. This should work still on oldcard, however.
sn_attach now requires that the resources be activated now, so adjust.

Provide a backwards compatible way to have the extra macro by defining
PCCARD_API_LEVEL 5 before including pccarddevs for driver writers that
want/need to have the same driver on 5 and 6 with pccard attachments.

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.

there's not dependencies on pccard symboles, such a dependency is not
necessary. This means that drivers that have multiple attachments can
not drag bogus devices into the kernel at load time.
We can't (yet) do this with pci and isa. Drivers written for them
actually do seem to have symbols that depend on these busses'
implementation code.
ndis not touched until other things can be tested.
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.
multicast hash are written. There are still two distinct algorithms used,
and there actually isn't any reason each driver should have its own copy
of this function as they could all share one copy of it (if it grew an
additional argument).
crashes that had sn0 as the irq that's being serviced, when there was
no sn0 in the system. This seems to prevent them. Also, we want to
wait until after we've registered with the network layer before we
turn on the interrupt spigot to avoid races.
if_xname, if_dname, and if_dunit. if_xname is the name of the interface

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.
