7a22215c53 Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

016385508f Better support for recent Myricom 10GbE NICs
- 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

88843c5481 Update to Myri10GE firmware version 1.4.33 from 1.4.29. Relevant changes include:
- 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

1e413cf932 Add optional support to mxge for MSI-X interrupts and multiple receive
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.

c587e59f20 - Fix a bug which could cause a panic when enabling LRO
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

053e637f86 Improve mxge receive performance:
- 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.

8fe615ba76 Firmware update & improvements to firmware selection:
- 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

0fa7f68197 - Updated to the latest myri10ge firmware
- 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.

5e7d85418b Update the mxge driver.
- 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.

6d87a65da4 - Complete the myri10ge -> mxge name change by doing a mechanical
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.

b2fc195e1b 10GbE mode driver and binary firmware for Myricom's PCI-express NICs.
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.
