eb6219e337 Implement minimal set of changes suggested by bz to make
mxge no longer depend on INET.

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.

f9ae02802f - Enable static building of mxge(4) and its firmware.
- Add custom .c wrappers for the firmware, rather than the standard
  firmware(9) generated firmware objects to work around toolchain
  problems on ia64 involving linking objects produced by
  ld -b -binary into the kernel.

- Move from using Myricom's ".dat" firmware blobs to using Myricom's
  zlib compressed ".h" firmware header files.  This is done to
  facilitate the custom wrappers, and saves a fair amount of wired
  memory in the case where the firmware is built in, or preloaded.

- Fix two compile issues in mxge which only appear on non-i386/amd64.

will load.

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.
