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.

Merge r283612:
Add SIOCGI2C ioctl support to the driver. Would work only on ConnectX-3
with fresh firmware. The low level code is based on code provided by
Mellanox.

Thanks to Mellanox and their distributor Must (http://mustcompany.ru)
for providing hardware.

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.

Various fixes to the mlxen(4) driver:
- Remove an incorrect assertion that can trigger when downing an interface.
- Stop the interface during detach to avoid panics when unloading the
driver.
- A few locking fixes to be more consistent with other FreeBSD drivers:
- Protect if_drv_flags with the driver lock, not atomic ops
- Hold the driver lock when adjusting multicast state.
- Hold the driver lock while adjusting if_capenable.

- Implement wake-on-lan support in mlxen.

- Correct the vlan filter programming. The device filter is built in
reverse order.
- Name the cq taskqueues according to whether they handle rx or tx.
- Default LRO to on.

- Don't use a separate set of rx queues for UDP, hash them into the same
set as TCP.
- Eliminate the fully linear non-scatter/gather rx path, there is no
harm in using arrays of clusters for both TCP and UDP.
- Implement support for enabling/disabling per-vlan priority pause and
queues via sysctl.

- Merge in OFED 1.5.3 from projects/ofed/head
