Setting this flag on an ethernet interface blocks transmission of packets
and discards incoming packets after BPF processing.
This is useful if you want to monitor network trafic but not interact
with the network in question.

if they are not going to cross over themselves. Also change how the list of
completed user threads is tracked and passed to the KSE. This is not
a change in design but rather the implementation of what was originally
envisionned.
aic79xx.c:
o Remove redundant ahd_update_modes() call.
o Correct panic in diagnostic should state corruption cause
the SCB Id to be invalid during a selection timeout.
o Add workaround for missing BUSFREEREV feature in Rev A silicon.
o Corect formatting nits.
o Use register pretty printing in more places.
o Save and restore our SCB pointer when updating the waiting queue
list for an "expected" LQ-out busfree.
o In ahd_clear_intstat, deal with the missing autoclear in the
CLRLQO* registers.
o BE fixup in a diagnostic printf.
o Make sure that we are in the proper mode before disabling
selections in ahd_update_pending_scbs.
o Add more diagnostics.
o task_attribute_nonpkt_tag -> task_attribute: we don't need a
nonpkt_tag field anymore for allowing all 512 SCBs to be
used in non-packetized connections.
o Negotiate HOLD_MCS to U320 devices.
o Add a few additional mode assertions.
o Restore the chip mode after clearing out the qinfifo so that
code using ahd_abort_scbs sees a consistent mode.
o Simplify the DMA engine shutdown routine prior to performing
a bus reset.
o Perform the sequencer restart after a chip reset prior to
setting up our timer to poll for the reset to be complete.
On some OSes, the timer could actually pre-empt us and order
is important here.
o Have our "reset poller" set the expected mode since there is
no guarantee of what mode will be in force when we are called
from the OS timer.
o Save and restore the SCB pointer in ahd_dump_card_state(). This
routine must not modify card state.
o Ditto for ahd_dump_scbs().
aic79xx.h:
o Add a few more chip bug definitions.
o Align our tag on a 32bit boundary.
aic79xx.reg:
aic79xx.seq:
o Start work on removing workarounds for Rev B.
o Use a special location in scratch from for stroring
our SCBPTR during legacy FIFO allocations. This corrects
problems in mixed packetized/non-packetized configurations
where calling into a FIFO task corrupted our SCBPTR.
o Don't rely on DMA priority to guarantee that all data in
our FIFOs will flush prior to a command completion notification
going out of the command channel. We've never seen this assumption
fail, but better safe than sorry.
o Deal with missing BUSFREEREV feature in H2A.
o Simplify disconnect list code now that the list will always
have only a single entry.
o Implement the AHD_REG_SLOW_SETTLE_BUG workaround.
o Swith to using "REG_ISR" for local mode scratch during
our ISR.
o Add a missing jmp to the data_group_dma_loop after our
data pointers have been re-initialized by the kernel.
o Correct test in the bitbucket code so that we actually
wait for the bitbucket to complete before signaling the
kernel of the overrun condition.
o Reposition pkt_saveptrs to avoid a jmp instruction.
o Update a comment to reflect that the code now waits for
a FIFO to drain prior to issuing a CLRCHN.
aic79xx_inline.h:
o Remove unused untagged queue handling code.
o Don't attempt to htole64 what could be a 32bit value.
aic79xx_pci.c:
o Set additional bug flags for rev A chips.
from DHCP in the event that no gateway is returned from DHCP, breaking
the assumption that we skip the routing insertion of the gateway
if the sin length is zero. Check also for s_addr of 0 to avoid the
"Oh no, adding my default route failed" panic, making it possible
to pxeboot machines on segments without default routes. Arguably
this could be a bug in pxeboot, or in the TUNABLE code, but this
makes my boxes boot.

- Make the VI asserts more orthogonal to the rest of the asserts by using a
new, common vfs_badlock() function and adding a 'str' arg.
- Adjust generated ASSERTS to match the new prototype.
- Adjust explicit ASSERTS to match the new prototype.
implement worthful VOP_BMAP() handler, so it expect the blkno not to be
changed by VOP_BMAP(). Otherwise, it'll have to find some tricky way to
determine if bp was VOP_BMAP()ed or not in VOP_STRATEGY().

aac driver dependent on the linux emulation module. This was
especially bad for the release engineers who tried to move the
aac driver from the kernel onto the drivers floppy. The linux
compat bits for this driver are now in their own driver, aac_linux.
It can be loaded as a module or compiled into the kernel. For
the latter case, the AAC_COMPAT_LINUX option is needed, along with
the COMPAT_LINUX option.
I've tested this in every configuration I can think of. This is an
MFC candidate for 4.7.
