bus driver will now remember the size of a BAR obtained during the initial
bus scan and use that size when doing lazy resource allocation rather than
resizing the BAR. The bus driver will now also report unallocated BARs to
userland for display by 'pciconf -lb'. Psuedo-resources that are not BARs
(such as the implicit I/O port resources for master/slave ATA controllers)
will no longer be listed as BARs in 'pciconf -lb'. During resume, BARs are
restored from their new saved state instead of having the raw registers
saved and restored across resume. This also fixes restoring BARs at
unusual loactions if said BAR has been allocated by a driver.
Add a constant for the offset of the ROM BIOS BAR in PCI-PCI bridges and
properly handle ROM BIOS BARs in PCI-PCI bridges. The PCI bus now also
properly handles the lack of a ROM BIOS BAR in a PCI-Cardbus bridge.

I have not properly thought through the commit. After r220031 (linux
compat: improve and fix sendmsg/recvmsg compatibility) the basic
handling for SO_PASSCRED is not sufficient as it breaks recvmsg
functionality for SCM_CREDS messages because now we would need to handle
sockcred data in addition to cmsgcred. And that is not implemented yet.

Introduce the AHB glue for Atheros embedded systems. Right now it's
hard-coded for the AR9130 chip whose support isn't yet in this HAL;
it'll be added in a subsequent commit.
Kernel configuration files now need both 'ath' and 'ath_pci' devices; both
modules need to be loaded for the ath device to work.

an underflow in the calculations in tcp_output() to decide if a window
update should be sent which would prevent the persist timer from being
started if data was pending and the other end of the connection advertised
an initial window size of 0.

will loop over that self-linked descriptor and treat it as "good enough"
for (incorrectly!) ACKing the frames in the block-ack.
Until I figure out how to work around this issue in the future, this counter
will tell me if packet RX processing ever gets to the point where it's
touching the self-linked descriptor. If there's ever enough packets to get
to that point, BA's will be invalid and likely very unhappy.

better than duplicating the code.

makes controller to receive bad frames and i82557 will also receive
bad frames since fxp(4) have to receive VLAN oversized frames. If
fxp(4) encounter DMA overrun error, the received frame size would
be 0 so the actual frame size after checksum field extraction the
length would be negative(-2). Due to signed/unsigned comparison
used in driver, frame length check did not work for DMA overrun
frames. Correct this by casting it to int.
While I'm here explicitly check DMA overrun error and discard the
frame regardless of result of received frame length check.

I'll clear how it's supposed to work with Bernhard and then look
at enabling this in the correct situations.
But this -does- enable HT RTS protection (using the appropriate legacy
rates) if this bit of code is enabled.
