- Update to firmware 1.4.39 for dual-chip NIC (10G-PCIE2-xxx)
support, and SFP+ i2c support
- Identify newer "B" NICs (10G-PCIEx-8B-x) correctly, rather than
mis-identifying them as "A" NICs (cosmetic only)
- Identify the IFM_10G_LRM ifmedia type, where applicable.
- Identify ifmedia types for SFP+ based NICs
- Update copyright

- Support for Myricom 10G-PCIE-8B NICs
- multi-slice firmware: fix a bug when the presence of 32-bit or
64-bit DMA addresses for interrupt queues and data is not uniform across
slices.
- Improves automatic selection between ethp_z8e/eth_z8e

queues (which we call slices). The NIC will steer traffic into up to
hw.mxge.max_slices different receive rings based on a configurable
hash type (hw.mxge.rss_hash_type).
Currently the driver defaults to using a single slice, so the default
behavior is unchanged. Also, transmit from non-zero slices is
disabled currently.
on an down mxge interface
- Fix a bug where mxge reported the link state as
active when it wasn't (after ifconfig down).
- Prevent spurious watchdog resets when link partner is not consuming
- Add support for CX4 and popular XFP media detection
- Update the firmware and associated header files to 1.4.25

- Update to the latest (1.4.18) f/w. This f/w introduces a new
receive mode which allows us to use FreeBSD's physically discontinuous
MJUM9BYTES clusters.
- Switch the driver from chaining MJUMPAGESIZE clusters to using
MJUM9BYTES clusters to avoid mbuf chaining overheads. Due to this
change, people running obsolete f/w images will be limited to an MTU of
PAGE_SIZE - 16.
- Add (disabled by default) support for Large Receive Offload.

- Update to latest (1.4.17) firmware.
- Use the new MXGEFW_CMD_UNALIGNED_TEST (added in firmare 1.4.16) to
have the firmware tell us if the PCIe chipset supports aligned PCIe
completions.
- Hard to maintain, and frequently out of date whitelist of PCIe
chipsets known to produce aligned completions removed, as it has been
replaced in its role of selecting the correct firmware to run by the
use of MXGEFW_CMD_UNALIGNED_TEST.
- Break the dma test out of mxge_reset() and into its own function
(mxge_dma_test()) so it can be used by both the normal DMA test, and
to run the unaligned test.
- Improved support for enabling ECRCs

- 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.
- 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.
