d7c5a620e2 ifnet: Replace if_addr_lock rwlock with epoch + mutex 
Run on LLNW canaries and tested by pho@

gallatin:
Using a 14-core, 28-HTT single socket E5-2697 v3 with a 40GbE MLX5
based ConnectX 4-LX NIC, I see an almost 12% improvement in received
packet rate, and a larger improvement in bytes delivered all the way
to userspace.

When the host receiving 64 streams of netperf -H $DUT -t UDP_STREAM -- -m 1,
I see, using nstat -I mce0 1 before the patch:

71e3c3083b sys/powerpc: further 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.

a1e1814d76 As <machine/pmap.h> is included from <vm/pmap.h>, there is no need to 
include it explicitly when <vm/pmap.h> is already included.

534c6b8916 Follow Linux by unconditionally stripping the RX vlan tag from incoming 
packets. It turns out that all firmware versions insert it, whether or not
they support VLAN tagging.

03479763b2 Import support for the Sony Playstation 3 using the OtherOS feature 
available on firmwares 3.15 and earlier.

Caveats: Support for the internal SATA controller is currently missing,
as is support for framebuffer resolutions other than 720x480. These
deficiencies will be remedied soon.

Special thanks to Peter Grehan for providing the hardware that made this
port possible, and thanks to Geoff Levand of Sony Computer Entertainment
for advice on the LV1 hypervisor.
