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.

We were only enabling it for revisions 0x0c and 0x0d, now it's
enabled for any 8255x NIC with a revision ID bigger than 0x0c. It
should be safe, and this is what Intel does in their open source
driver.

- Don't waste time calling bus_dmamap_load_mbuf() if we know the mbuf
chain is too long to fit in a TX descriptor, call m_defrag() first.
- Convert fxp(4) to use bus_dmamap_load_mbuf_sg().

time. While I'm here, slightly improve the style in fxp_attach().

Move code to the right location and disallow the use of the 82503
serial mode if the sc->revision field is 0 again. This makes fxp(4)
work correctly with ATMEL 350 93C46 cards (3 port 82559 based with a
82555 PHY), as well as with the older ATMEL 220 93C46 (same flavour)
and with the even older 10Mbps-only 82557 cards with the 82503 serial
interface.

datasheet says it is only valid for such chipsets and shouldn't be used

work at 10Mbit.

sysctls were global (hw.fxp_rnr and hw.fxp_noflow), all of them are
now per-device. Sample output of "sysctl dev.fxp0" with this patch,

dev.fxp0.int_delay: 1000

In particular, disabling it was likely to break configurations
involving ng_vlan(4) since the latter couldn't control
