it should have been 512K. This doesn't actually change the code, but

Copy wi_{dst,src}_addr from struct wi_frame into faked-up ether_header
instead of addr1 and addr2. THis means that tcpdump -e will show the
correct MAC address for communications with access points instead of showing
the BSSID.
In the future there should be 802.11 support for bpf/libpcap/tcpdump,
but that is aways down the road.

overflow the request queue. The reason we want to do this is that we
now push out completed CTIOs as we complete them- this gets the QLogic
working on them quicker. So we need to know whether we can put the entire
burrito out before we start.
We now support conjoint status with data for the last CTIO for both Fibre
Channel and SCSI. Leave the old code in place in case we need to go back
(minor 3 line ifdef).
Ultra-ultra important- *don't* set rq->req_seg_count for non-data
target mode requests in isp_pci_dmasetup. D'oh- this is actually
the tag value area for a CTIO. What *was* I thinking? Boy howdy
does both aic7xxx and sym get awfully unhappy when on reconnect
you give them a constant '1' for a tag value.
function- we did it a bit cleaner. We only use this if a CTIO completes with
!CT_OK state. We now have managed to get away without having to poke around
and trying to find the original ATIO- the csio we're using has the tag_id
and lun values with it which is mostly what we need when we do the putback.
Make sure we correctly propagate AT_TQAE->CT_TQAE for tags. Make sure
we call ISP_DMAFREE only if we had DATA to move.
tag is active for an ATIO, and say that you want to reconnect with
a tag value in a CTIO have *never* been exercised until now. This lossage
derived from Solaris code where this stuff originally came from that is
about 7 years old. Amazing.
We now bundle the incoming tag (legal values are 0..256) as the low
16 bits of the ccb_accept_tio's at_tagid while we put the firmware
handle for this ATIO in the top 16 bits- define some macros to make
this cleaner.
Complete some Ansification.
Redo establishment of default SCSI parameters whether or not
we've been compiled for target mode. Unfortunately, the Qlogic
f/w is confused so that if we set all targets to be 'safe' (i.e.,
narrow/async), it will also then report narrow, async if we're
contacted in target mode from that target (acting in initiator
role). D'oh!
Fix ISPCTL_TOGGLE_TMODE to correctly enable the right channel for

- Added 4 speaker enable to initialization sequence.

problem this card has sampling at 44.1kHz. With any form of delay,
skew relative to system clock at 44.1kHz is usually in range 0-25%

- Changed structs cmi_* to sc_*.

aic7xxx_pci.c:
Enable board generation of interrupts only once our handler is
in place and all other setup has occurred.
aic7xxx.c:
More conversion of data types to ahc_* names. tmode_tstate and
tmode_lstate are the latest victims.
Clean up the check condition path by branching early rather
than indenting a giant block of code.
Add support for target mode initiated sync negotiation.
The code has been tested by forcing the feature on for
all devices, but for the moment is left inaccesible until
a decent mechanism for controlling the behavior is complete.
Implementing this feature required the removal of the
old "target message request" mechanism. The old method
required setting one of the 16 bit fields to initiate
negotiation with a particular target. This had the nice
effect of being easy to change the request and have it
effect the next command. We now set the MK_MESSAGE bit
on any new command when negotiation is required. When
the negotiation is successful, we walk through and clean
up the bit on any pending commands. Since we have to walk
the commands to reset the SCSI syncrate values so no additional
work is required. The only drawback of this approach is that
the negotiation is deferred until the next command is queued to
the controller. On the plus side, we regain two bytes of
sequencer scratch ram and 6 sequencer instructions.
When cleaning up a target mode instance, never remove the
"master" target mode state object. The master contains
all of the saved SEEPROM settings that control things like
transfer negotiations. This data will be cloned as the
defaults if a target mode instance is re-instantiated.
Correct a bug in ahc_set_width(). We neglected to update
the pending scbs to reflect the new parameters. Since
wide negotiation is almost always followed by sync
negotiation it is doubtful that this had any real
effect.
When in the target role, don't complain about
"Target Initiated" negotiation requests when an initiator
negotiates with us.
Defer enabling board interrupts until after ahc_intr_enable()
is called.
Pull all info that used to be in ahc_timeout for the FreeBSD
OSM into ahc_dump_card_state(). This info should be printed
out on all platforms.
aic7xxx.h:
Add the SCB_AUTO_NEGOITATE scb flag. This allows us to
discern the reason the MK_MESSAGE flag is set in the hscb
control byte. We only want to clear MK_MESSAGE in
ahc_update_pending_scbs() if the MK_MESSAGE was set due
to an auto transfer negotiation.
Add the auto_negotiate bitfield for each tstate so that
behavior can be controlled for each of our enabled SCSI
IDs.
Use a bus interrupt handler vector in our softc rather
than hard coding the PCI interrupt handler. This makes
it easier to build the different bus attachments to
the aic7xxx driver as modules.
aic7xxx.reg:
Remove the TARGET_MSG_REQUEST definition for sequencer ram.
aic7xxx.seq:
Fix a few target mode bugs:
o If MK_MESSAGE is set in an SCB, transition to
message in phase and notify the kernel so that
message delivery can occur. This is currently
only used for target mode initiated transfer
negotiation.
o Allow a continue target I/O to compile without
executing a status phase or disconnecting. If
we have not been granted the disconnect privledge
but this transfer is larger than MAXPHYS, it may
take several CTIOs to get the job done.
Remove the tests of the TARGET_MSG_REQUEST field in scratch ram.
aic7xxx_freebsd.c:
Add support for CTIOs that don't disconnect. We now defer
the clearing of our pending target state until we see a
CTIO for that device that has completed sucessfully.
Be sure to return early if we are in a target only role
and see an initiator only CCB type in our action routine.
If a CTIO has the CAM_DIS_DISCONNECT flag set, propogate
this flag to the SCB. This flag has no effect if we've
been asked to deliver status as well. We will complete
the command and release the bus in that case.
Handle the new auto_negotiate field in the tstate correctly.
Make sure that SCBs for "immediate" (i.e. to continue a non
disconnected transaction) CTIO requests get a proper mapping
in the SCB lookup table. Without this, we'll complain when
the transaction completes.
Update ahc_timeout() to reflect the changes to ahc_dump_card_state().
aic7xxx_inline.h:
Use ahc->bus_intr rather than ahc_pci_intr.
decode the BIOS and firmware version and announce the board as HP NetRaid.
This has been tested with a NetRaid 3si controller, the BIOS/firmware
printout should also work for other NetRaid controllers but the type
detection for other NetRaids (such as the 1si) will not work due to the
lack of hardware.
