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.

o Grab the MAC address out of the CIS if the card has the special
3Com 0x88 tuple. Most 3Com cards don't have this tuple, but we
prefer it to the eeprom since it only appears to be present when
the eeprom doesn't have the info. So far, I've only observed this
on my 3C362 and 3C362B cards, but the NetBSD driver implies that
the 3C362C also has this tuple, and that some 3C574 cards do too (none
of mine do). ep_pccard_mac was written after looking at the NetBSD
code.
o Store the enet addr in the softc for this device, so we can use the
overridden MAC to set the station address.
o Create a routine to set the station address and use it where we need it.
o setup the cmd shitfs and such before we call ep_alloc(), and remove
setting up the cmd shift value there. It initializes to 0, and those
attachments that need to frob it do so before calling ep_alloc.
o Remove some obsolete comments
o No longer a need to export ep_get_macaddr, so make it static
o ep_alloc already grabs the EEPROM id, so we don't need to grab it again
in ep_pccard_attach.
o eliminate unit, it isn't needed, fix some printfs to be device_printf
instead.

which command to use to read the eeprom and which devices have an MII.
Simplify code by no longer using the OLDCARD compat rouintes (I don't
know if this breaks OLDCARD on pc98 or not, but OLDCARD on pc98 days
are numbered, I hope). This also removes a number of kludges that we
had before because they are OBE. Add a convenience routine to lookup
the device to avoid many casts in many places.

o Rename get_e() to ep_get_e() to avoid namespace pollution.

Provide a backwards compatible way to have the extra macro by defining

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.

o Remove redundant $FreeBSD$
o Better comments about ep_get_macaddr.
o remove one tab in a switch statement (style only)
o Recognize ID 0x0035 as the device ID for the 3CXEM556 that I have. This
makes the 3CXEM556 work for me. Not 100% sure this is the assigned ID,
as I don't have the datasheets for this part, but it does work and get
the correct ethrnet address.
o Comment about the whole fake IRQ 3 thing. some need it, some don't, all
work with it.
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.
This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

flag'ed INTR_MPSAFE. In ep_if_start(), use the IF_DEQUEUE macro to
grab the next mbuf to send, and use IF_PREPEND if the card is busy
and we actually can't handle it right now.
The old code was first getting the mbuf by taking it from the queue
without using the macros, thus without locking, and without removing
it from the queue either. It was later assuming that IF_DEQUEUE would
give him this same mbuf.
