32 (2^n)). For reasons that are not obvious to me this fixes the driver

- In the watchdog routine, only reset the chip if the blob doesn't complete
any pending tx completions rather than requiring it to complete all of
the pending tx completions.

OS dependent layer. Thus, the watchdog timer can go off when the tx
engine is working fine but the OS dependent layer just hasn't been called
to cleanup finished tx transactions. To workaround this, when the watchdog
fires, poke the binary blob to force it to flush any pending tx
completions. If this drops the pending tx count to zero then just return
without logging a message or resetting the chip.
This reportedly fixes the 'device timeout()' errors with at least several
NF4 nve(4) parts.

working at all and only saw "nve0: device timeout (N)" messages.
- Setup PHY before handing control to NVidia API setting
speed, duplex, enabling interrupts, etc.
- Add restriction of MAXADDR_32BIT for high address to contigmalloc
to make the driver work on machines with 4+GB of memory.

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.

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.

rather than in ifindex_table[]; all (except one) accesses are
through ifp anyway. IF_LLADDR() works faster, and all (except
one) ifaddr_byindex() users were converted to use ifp->if_addr.
- Stop storing a (pointer to) Ethernet address in "struct arpcom",
and drop the IFP2ENADDR() macro; all users have been converted
to use IF_LLADDR() instead.

could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash. Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.

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.

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.
