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.

dc0: MII without any PHY!
We have to enable the connection to the MII first. Doing so fixes the
problem cards without breaking the older, working cards.

This adds support for the SiS intergrated NIC on some Athlon64 motherboards.
The MAC address is stored in the APC CMOS RAM and this fixes the
sis driver ending up with a 00:00:00:00:00:00 MAC address.

Do our best to plug some memory leaks (VPD data, jumbo memory buffer,...).
Log if we cannot free because memory still in use[1].
Change locking to avoid ''acquiring duplicate lock of same
type: "network driver"'' and potential deadlock. Also seems to fix LOR #063.
[1] This change does not solve problems if buffers are still in use when
unloading if_sk.ko. There is ongoing work which will address jumbogram
allocations in a more general way.

asks that each buffer be (2048 * 256) bytes long. I suspect that alignment
isn't a real requirement since busdma only recently started honoring it. The
size is also bogus. Fix both of these and stop busdma from trying to
exhaust the system memory pool with bounce pages.
