17a1391990 The IO_NOWDRAIN and B_NOWDRAIN hacks are no longer needed to prevent
deadlocks with vnode backed md(4) devices because md now uses a

95c9929a3b aic79xx.c:
Use the special LUNLEN_SINGLE_LEVEL constant for
	post Rev A4 hardware for single byte luns.  Without
	this change, Rev B hardware would place the single
	byte of lun data in byte 0 of the lun structure when
	it should be in byte 1.  Since there are few if any
	devices on the market that support multiple luns in
	target mode, the corrupted lun field (which was only
	corrupted for non-zero luns) wasn't hurting us.

4fb8dd97a7 Fix support for 256 MB aperture sizes on chipsets such as the 845 and
865.  The APSIZE register has a variable-sized field of enabled bits.
To figure out how many bits a specific host bridge supports, write the
maximum width and see how many bits are set in the hardware.  We then
use this mask for setting and getting the aperture size.  Prior to this,
the agp(4) driver would treat an aperture size of 256 MB as 128 MB and
would not allocate enough physical memory for the GART as a result.

333f04d935 Correct/Simplify ignore wide residue message handling
aic79xx.c:
	In ahd_handle_ign_wide_residue():
	o Use SCB_XFERLEN_ODD SCB field to determine transfer
	  "oddness" rather than the DATA_COUNT_ODD logic.
	  SCB_XFERLEN_ODD is toggled on every ignore wide
	  residue message so that multiple ignore wide residue
	  messages for the same transaction are properly supported.
	o If the sg list has been exausted, the sequencer
	  doesn't bother to update the residual data count
	  since it is known to be zero.  Perform the zeroing
	  manually before calculating the remaining data count.
	o Use multibyte in/out macros instead of shifting/masking
	  by hand.

aic79xx_inline.h:
	In ahd_setup_scb_common(), setup the SCB_XFERLEN_ODD field.

aic79xx.reg:
	Use the SCB_TASK_ATTRIBUTE field as a bit field in the
	non-packetized case.  We currently only define one bit,
	SCB_XFERLEN_ODD.

	Remove the ODD_SEG bit field that was used to carry the odd
	transfer length information through the SG cache.  This
	is obviated by SCB_XFERLEN_ODD field.

	Remove the DATA_COUNT_ODD scratch ram byte that was used
	dynamicaly compute data transfer oddness.  This is obviated
	by SCB_XFERLEN_ODD field.

aic79xx.seq:
	Remove all updates to the DATA_COUNT_ODD scratch ram field.
	Remove all uses of ODD_SEG.  These two save quite a few
	sequencer instructions.

	Use SCB_XFERLEN_ODD to validate the end of transfer
	ignore wide residue message case.

	o Ensure that SG_LIST_NULL is cleared in the
	  residual sg pointer for "mid-transfer" ignore
	  wide residue cases.
	o Use multibyte in/out macros instead of shifting/masking
	  by hand.

aic7xxx.h:
	Modify the SCB_GET_LUN() macro to mask the lun hardware
	SCB field with LID.  This leaves two bits in the LUN
	field that can be used for other purposes.

aic7xxx.reg:
	Change LID to be 0x3F.  This is the maximum supported
	lun size for non-packetized SCSI.  Map the top bit
	of the lun to SCB_XFERLEN_ODD.  The host must set
	this bit whenever a transfer is an odd length.

	Remove the ODD_SEG bit field that was used to carry the odd
	transfer length information through the SG cache.  This
	is obviated by SCB_XFERLEN_ODD field.

	Remove the DATA_COUNT_ODD scratch ram byte that was used
	dynamicaly compute data transfer oddness.  This is obviated
	by SCB_XFERLEN_ODD field.

aic7xxx.seq:
	Be more careful in our handling of the SCB_LUN field.  It
	must be masked with LID if only lun information is desired.

	Remove all updates to the DATA_COUNT_ODD scratch ram field.
	Remove all uses of ODD_SEG.  These two save quite a few
	sequencer instructions.

	Use SCB_XFERLEN_ODD to validate the end of transfer
	ignore wide residue message case.

a3f571b832 Change hadling of the Rev. A packetized lun output bug
to be more efficient by having the sequencer copy the
single byte of valid lun data into the long lun field.

aic79xx.c:
	Memset our hardware SCB to 0 so that untouched
	fields don't confuse diagnostic output.  With the
	old method for handling the Rev A bug, if the long
	lun field was not 0, this could result in bogus
	lun information being sent to drives.

	Use the same SCB transfer size for all chip types
	now that the long lun is not DMA'ed to the chip.

a35e7eaa1a Always set the hardware parse bit in the IPCB structure when this
structure, which is new to the 82550 and 82551, is used to transmit
a packet.  This appears to fix the packet truncation problem that was
observed when using 82550-based fxp cards to transmit ICMP or fragmented
UDP packets of certain lengths which only had one to three bytes in the
second and final mbuf of the packet.  This matches a note in the "Intel
8255x 10/100 Mbps Ethernet Controller Family Open Source Software Developer
Manual", which says that the hardware parse bit should be set when sending
these types of packets.

There have also been unconfirmed reports of similar problems when
transmitting TCP packets, which should not be affected by the above
mentioned change because the hardware parse bit was already being set
if the stack requested hardware checksumming of the packet.  If the
problem remains, the use of the IPCB structure can be disabled to
cause the driver to fall back to using the older 82559 interface with
82550-based cards by setting
        hint.fxp.UNIT_NUMBER.ipcbxmit_disable
to a non-zero value at boot time, or using kenv to set this variable
before using kldload to load the fxp driver.

f9aedaa4ba Ignore the 'must allocate below 1MB' flag for the TPL_BAR_REG. It is
set on realtek cards, but they work without it (and don't work with
it).  The standard seems to imply that this is just a hint anyway, so
this should be harmless.  It doesn't appear to be set on any other
cardbus cards that I have (or have seen).

This should make the rl based CardBus cards work again.  I've been
running it for about a month now.
