- Copy stable/10@296371 to releng/10.3 in preparation for 10.3-RC1
builds.
- Update newvers.sh to reflect RC1.
- Update __FreeBSD_version to reflect 10.3.

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.

MFC r276749:
Fixes and updates for the Linux compatibility layer:
- Remove unsupported "bus" field from "struct pci_dev".
- Fix logic inside "pci_enable_msix()" when the number of allocated
interrupts are less than the number of available interrupts.
- Update header files included from "list.h".
- Ensure that "idr_destroy()" removes all entries before destroying
the IDR root node(s).
- Set the "device->release" function so that we don't leak memory at
device destruction.
- Use FreeBSD's "log()" function for certain debug printouts.
- Put parenthesis around arguments inside the min, max, min_t and max_t macros.
- Make sure we don't leak file descriptors by dropping the extra file
reference counts done by the FreeBSD kernel when calling falloc()
and fget_unlocked().

MFC r268316:
Fix OFED startup order: All SYSINIT()'s and modules should be loaded
prior to starting "/sbin/init" which will run all the "/etc/rc.d/xxx"
scripts. Else there can be a race configuring the interfaces via
"/etc/rc.conf".

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.

Rework the previous fix for the IB vs Ethernet sysctl handler to be more
generic and apply to all sysfs attributes:
- Use sysctl_handle_string() instead of reimplementing it.
- Remove trailing newline from the current value before passing it to
userland and append a newline to the new string value before passing it
to the attribute's store function.
- Don't leak the temporary buffer if the first error check triggers.
- Revert earlier change to mlx4 port mode handler.

Allow mlx4 devices to switch from Ethernet to Infiniband (and vice versa):
- Fix sysctl wrapper for sysfs attributes to properly handle new string
values similar to sysctl_handle_string() (only copyin the user's
supplied length and nul-terminate the string).
- Don't check for a trailing newline when evaluating the desired operating
mode of a mlx4 device.
