for pci_cfg_restore() to be exported. It was tested using a
hackily accessed pci_cfg_restore().
- Add ifmedia_removeall() to mxge_detach() in order to stop leaking
an ifaddr
- Fix a small acounting bug introduced by the locking code shuffle
which could cause spurious watchdog resets now that we have a
watchdog.

locking in preparation for adding a watchdog handler (callouts must
not use sleepable locks). This required shuffling memory and
interrupt allocation to the attach routine rather than if_ioctl so as
to avoid potential sleeps while bringing up the interface.
- initialize ifq_drv_maxlen correctly
- mark the interface as jumbo capable
- keep stats on the number of times the hw transmit queue filled and
was restarted.
- Fix bug preventing adoption of running firmware
- Set PCIe max read request size to 4KB
- Read PCIe link width from config space
- Assume aligned completions from the southbridge ports
of intel E5000 chips
- Use aligned firmware when link width is x4 or less
- Add hw.mxge.force_firmware tunable to allow user to force
selection of aligned (or unaligned) firmware
long being DMA'ed 2 (or 1) bytes past the end of the mbuf and corrupting
random kernel memory. I had forgotten about the 2 bytes of implict
padding the firmware assumes.

- Added support for multicast filtering, now that the firmware
supports it. Note that this is not yet tested, as multicast
seems to panic -current (even w/o mxge loaded)
- Added workaround to cope with different irq data struct size on
pre-multicast firmware which can found running on nics.
- Added Intel E5000 PCIe chipsets to list providing aligned completions.
- Replaced various magic constants with #defines, now that they are
defined in the firmware headers.
in the transmit busdma tag, so I moved the segment list off the
stack.
- Fixed transmit routine to ensure it doesn't read past the end
of an mbuf when parsing headers.
- Corrected handling of odd length segments. Setting MXGEFW_FLAGS_ALIGN_ODD
is required only when offloading the checksum of that frame.

- Copy ethernet firmware down in small chunks so as to avoid bugs
in early versions of the bootstrap firmware.
- Attempt to "adopt" the running firmware if we cannot load a suitable
firmware image via firmware(9).
- Separate firmware validation into its own routine, and check the
major/minor driver/firmware ABI version.
!IFQ_DRV_IS_EMPTY(). Taking this into account, I re-structured the
transmit routine so as to avoid adding another if/then in the
critical path.
Thanks to brueffer for showing my how to test with altq/pf.
- Update the firmware to the latest released firmware
(1.4.3), which corresponds to the firmware in the
latest shipping drivers from Myricom. This firmware
fixes several bugs in the firmware's PCI-e implementation,
and it also changes the driver/firmware interface:
o TSO was added, and changed the format of the transmit
descriptors.
o The firmware no longer counts transmits descriptors,
but frames. So the driver needs to keep a count
of the number of frames sent.
o The weird interrupt strategy changed to a normal receive
return ring. This ring is much bigger, and we may be
able to support DEVICE_POLLING.
o Myricom's header files changed the name of firmware
related #define's and enums (s/_MCP_/FW_).
- Stopped spamming the console with lots of printfs unless
mxge_verbose (or bootverbose) is set.
- Made additional information available via sysctl, including
the results of a PCI-e DMA benchmark run at device reset.
- Decreased the excessively long timeouts when sending commands
from 2 seconds to 20ms.

s/myri10ge/mxge/g replacement in the myri10ge files. A few contuation
lines were joined because of the regained columns.
- Hook the mxge driver back to the build.
More info regarding these nics can be found at http://www.myri.com.
Please note that the files
sys/dev/myri10ge/{mcp_gen_header.h,myri10ge_mcp.h} are internally
shared between all our drivers (solaris, macosx, windows, linux, etc).
I'd like to keep these files unchanged, so I can just import newer
versions of them when the firmware API/ABI changes. This means I'm
stuck with some of the crazy-long #define names, and possibly
non-style(9) characteristics of these files.
Many thanks to mlaier for doing firmware(9) just as I
needed it, and to scottl for his helpful review.
