MFC r290710, r291694, r291699 and r291793:
- Fix print formatting compile warnings for Sparc64 and PowerPC platforms.
- Updated the mlx4 and mlxen drivers to the latest version, v2.1.6:
- Added support for dumping the SFP EEPROM content to dmesg.
- Fixed handling of network interface capability IOCTLs.
- Fixed race when loading and unloading the mlxen driver by applying
appropriate locking.
- Removed two unused C-files.
- Convert the mlxen driver to use the BUSDMA(9) APIs instead of
vtophys() when loading mbufs for transmission and reception. While at
it all pointer arithmetic and cast qualifier issues were fixed, mostly
related to transmission and reception.
- Fix i386 build WITH_OFED=YES. Remove some redundant KASSERTs.

Update OFED to Linux 3.7 and update Mellanox drivers.

Update the OFED Infiniband core to the version supplied in Linux
version 3.7.

The update to OFED is nearly all additional defines and functions
with the exception of the addition of additional parameters to
ib_register_device() and the reg_user_mr callback.

In addition the ibcore (Infiniband core) and ipoib (IP over Infiniband)
have both been made into completely loadable modules to facilitate
testing of the OFED stack in FreeBSD.

Finally the Mellanox Infiniband drivers are now updated to the
latest version shipping with Linux 3.7.
