630d0d0838 Update the Tigon 1 and 2 driver to use the sf_buf API for implementing
zero-copy receive of jumbo frames.  This eliminates the need for the
jumbo frame allocator implemented in kern/uipc_jumbo.c and sys/jumbo.h.
Remove it.

Note: Zero-copy receive of jumbo frames did not work without these changes;
I believe there was insufficient locking on the jumbo vm object.

36c3b3ee0b Commit more debugging output. This is a little bit of using a large hammer,
but sk(4) is so prevalent on AMD64 motherboards we need to reduce the number
of round trips in the mailing lists trying to get sufficient information to
make sure we've got a handle on all the problems and are working towards
making sk(4) solid.

0447144e4c Another missing ! in front of IFQ_DRV_IS_EMPTY, this time in an even more
sensitive, but less excercised location (the watchdog). While here use the
*_start_locked function directly to avoid drop, grab, drop lock.

I have to be very careful with future ALTQ patches!

586226b93c Forcibly disable interrupts, if we find ourselves servicing one when
the device is suspended or shutting down. This will need to be rethought
slightly if we implement suspend/resume support within vr(4).
This appears to fix the vr_shutdown() panic on SMP machines.

My theory here is there's a race somewhere during vr_detach() with
vr_intr() in the SMP case which was sometimes being triggered,
although quite why this was happening is unclear (vr_stop() also
explicitly disables interrupts by writing to the IMR register).

MFC-to-RELENG_5* candidate.

ab5364e451 fix (for me) the problems where if_de gets really slow after time
(usually taking 20 seconds to transmit a packet).. no longer fall back
to only transmitting one packet (instead of the entire queue) after we
have processed the entire send queue...  I have no idea why we didn't
start seeing this problem ~6 years ago when this code was introduced...

cf25dec606 Do not call xl_init_locked() unconditionally when we are bringed UP. Call
it only if we weren't UP before. In some cases xl_init causes long media
re-negotiation, and ppp(8) fails to open PPPoE connection because it sets
IFF_UP every time before opening PPPoE connection.

3de2c5e7d8 if_dc includes locking, but that locking is disabled by a #ifdef
by default.  As such, mark if_dc as IFF_NEEDSGIANT until such
time as appropriate locking review and testing can take place,
and the locking can be enabled by default.

cd9e845490 - Make OF_getetheraddr() honour the "local-mac-address?" system config
variable. If set to "true" OF_getetheraddr() will now return the unique
  MAC address stored in the "local-mac-address" property of the device's
  OFW node if present and the host address/system default MAC address if
  the node doesn't doesn't have such a property. If set to "false" the
  host address will be returned for all devices like before this change.
  This brings the behaviour of device drivers for NICs with OFW support/
  FCode, i.e. dc(4) for on-board DM9102A on Sun machines, gem(4) and hme(4),
  regarding "local-mac-address?" in line with NetBSD and Solaris.
  The man pages of the respective drivers will be updated separately to
  reflect this change.
- Remove OF_getetheraddr2() which was used as a stopgap in dc(4). Its
  functionality is now part of OF_getetheraddr().
