in the RX path when doing 11n and block-ack'ed frames. Apparently, the MAC
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.

engine is stopped so using a common function to handle the job is
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.

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.
instead of 0x100000. As a side effect, an amd64 kernel now loads at
physical address 0x200000 instead of 0x100000. This is probably for the
best because it avoids the use of a 2MB page mapping for the first 1MB of
the kernel that also spans the fixed MTRRs. However, getmemsize() still
thinks that the kernel loads at 0x100000, and so the physical memory between
0x100000 and 0x200000 is lost. Fix this problem by replacing the hard-wired
constant in getmemsize() by a symbol "kernphys" that is defined by the
linker script.

Fix this by adding sc_name field to struct g_gate_softc. In

not sc_name points to provider name stored in the local array.

just for Redboot.
At some point we're going to need to build options for different
boot environments - for example, the UBoot setups I've seen simply
have the MAC address hard-coded at a fixed location in flash.
The OpenWRT support simply yanks the if_arge MAC directly from that
in code, rather than trying to find a uboot environment to pull it
from.
memory detected from Redboot, or overrides the "otherwise" case
if no Redboot information was found.
Some AR71XX platforms don't use Redboot (eg TP-LINK devices using
UBoot; some later Ubiquiti devices which apparently also use
UBoot) and at least one plain out lies - the Ubiquiti LS-SR71A
Redboot says there's 16mb of RAM when in fact there's 32mb.
A more "clean" solution will be needed at a later date.
The AR913x/AR724x USB lives at a different offset to the AR71xx
USB, so this needs to be either adjusted for in a subsequent
commit, or updated in hints for kernels compiled for those
platforms.

syncing for Hummingbird and Sabre bridges should be applied with every

for devices behind PCI-PCI bridges only as suggested by the documentation

I'd need this for a Sun Fire 3800, which then turned out to not being
equipped with such a bridge though. The support for these should be
complete but given that it hasn't actually been tested probing is
disabled for now.
This required a way to alter the XMITS configuration in case a PCI-X
device is found further down the device tree so the sparc64 specific
ofw_pci kobj was revived with a ofw_pci_setup_device method, which is
called by the ofw_pcibus code for every device added.
- A closer inspection of the OpenSolaris code indicates that consistent
DMA flushing/syncing as well as the block store workaround should be
applied with every BUS_DMASYNC_POSTREAD instead of in a wrapper around
interrupt handlers for devices behind PCI-PCI bridges only as suggested
by the documentation (code for the latter actually exists in OpenSolaris
but is disabled by default), which also makes more sense.
- Add a workaround for Casinni/Skyhawk combinations. Chances are that
this solves the crashes seen when using the the on-board Casinni NICs
