Ensure the received IP header gets 32-bits aligned.

The FreeBSD's TCP/IP stack assumes that the IP-header is 32-bits aligned
when decoding it. Else unaligned 32-bit memory access can happen, which
not all processor architectures support.

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.

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.

Fix multiple incorrect SYSCTL arguments in the kernel:

- Wrong integer type was specified.

- Wrong or missing "access" specifier. The "access" specifier
sometimes included the SYSCTL type, which it should not, except for
procedural SYSCTL nodes.

- Logical OR where binary OR was expected.

- Properly assert the "access" argument passed to all SYSCTL macros,
using the CTASSERT macro. This applies to both static- and dynamically
created SYSCTLs.

- Properly assert the the data type for both static and dynamic
SYSCTLs. In the case of static SYSCTLs we only assert that the data
pointed to by the SYSCTL data pointer has the correct size, hence
there is no easy way to assert types in the C language outside a
C-function.

- Rewrote some code which doesn't pass a constant "access" specifier
when creating dynamic SYSCTL nodes, which is now a requirement.

- Updated "EXAMPLES" section in SYSCTL manual page.

Defer start/stop port to workqueues.

We need to do this because the Linux compat layer uses sx(9) for
mutex, however the lagg code uses rmlocks and calls into the mellanox
driver. This causes deadlock due to sleeping while holding a rmlock.

Do not use a sleep lock when protecting the driver flags.

This was causing a locking issue with lagg

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.

- Implement wake-on-lan support in mlxen.

- 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
