81b6f8d5df Fix an off by one error in struct nve_tx_desc's frags[] array as a result
of the nvenet lib upgrade (the constant went from 63 (2^n - 1) to
32 (2^n)).  For reasons that are not obvious to me this fixes the driver
on at least some NICs.

5714e9ea59 - Don't make the driver lock recursive, it shouldn't be recursively
acquired anywhere in the driver now.
- Axe the spin mutex used for the nve_oslock*() routines.  The driver lock
  already provides sufficient synchronization.
- Don't mess around with IFF_UP when the link state changes.  IFF_UP is
  an administrative flag, not a link status indicator.

aed0e2071f Overhaul nve(4) locking to make it more like other ethernet drivers in
the tree.
- Add locked variants of nve_start(), nve_init(), and nve_ifmedia_upd().
- Use callout_* to manage callouts rather than timeout(9).
- Mark interrupt handler MPSAFE (IFF_NEEDGIANT was already clear).
- Lock the driver lock in driver entry points such as the interrupt
  handler, if_start, and if_init rather than locking the driver mutex
  in the various work functions called by the binary blob.  The spin lock
  used by the binary block can probably be stubbed out now.
- Use IFQ_DRV_IS_EMPTY() macro rather than doing it by hand.
- Fix locking in detach.
- Remove some unused fields from the softc.

fc74a9f93a 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.
