Code Issues Releases Activity

- Enable static building of mxge(4) and its firmware.

Browse Source 
- 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.
