sys: Remove $FreeBSD$: one-line .c pattern

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

ofed: Mechanically convert to IfAPI

Summary:
Because of the intricacies of this code it wasn't purely scripted, but
instead hand-mechanical.

ipoib: Fix incorrectly computed IPOIB_CM_RX_SG value.

The computed IPOIB_CM_RX_SG is too small. It doesn't account for fallback
to mbuf clusters when jumbo frames are not available and it also doesn't
account for the packet header and trailer mbuf.

This causes a memory overwrite situation when IPOIB_CM is configured.

While at it add a kernel assert to ensure the mapping array is not overwritten.

Make sure the VNET is properly set when reaping mbufs in ipoib.
Else the following panic may happen:

panic()
icmp_error()
ipoib_cm_mb_reap()
linux_work_fn()
taskqueue_run_locked()
taskqueue_thread_loop()
fork_exit()
fork_trampoline()

Fix missing epochification of the ipoib code after r353292.

Make sure the transmit loop doesn't get starved in ipoib.

When the software send queue gets filled up, callbacks to
if_transmit will stop. Make sure the transmit callback
routine checks the send queue and outputs any remaining
mbufs. Else the remaining mbufs may simply sit in the
output queue blocking the transmit path.

sys: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Make sure all tasks are cancelled synchronously in ipoib to avoid
use after free.

Mechanically convert to if_inc_counter().

Add OFED and the associated options and drivers to x86 LINT builds:
- Mark 'sdp' as requiring 'inet'.
- Always include "opt_inet.h" and "opt_inet6.h" and modify the IB
driver Makefiles to honor WITH/WITHOUT_INET/INET6/_SUPPORT options
to determine what should be enabled during a module build.
- Fix the mlxen(4) driver and the core IB code to compile without
if INET is disabled (including when both INET and INET6 are disabled).

Don't update if_obytes when transmitting packets. That is already done
in IFQ_HANDOFF() when the packet is passed to the start routine, so doing
it here resulted in double counting.
