This driver hasn't been relevant in almost 15 years. It was for a product on the
shelves for about 6 months in 2003/2004. I've not updated the driver since then,
and have had nobody talk to me about it since maybe 2006 or 2007. It doesn't
implement a standard interface, and can be better done with libusb. All the
action has moved to webcamd for newer, more fully featured hardware. It makes no
appearances in the nycbug dmesg archive.

make kernels was originally documented (in commit r295099) as the same as make
universe -DJUST_BUILD_KERNELS. However, it used the UNIVERSE_TARGET=buildkernel
which is subtly different in that it also builds the toolchains and doesn't
build the LINT modules unless they happened to already exist in the tree. This
unbreaks POLA and just builds the kernels, including LINT, now rather than all
that other stuff as well. When the commit originally happened, the two just
differed by the LINT bug. r335711 introduced the universe dependency on the
toolchain that wasn't present before, which diverged the two further. This
restores the original intent of r295099.

Reported by: Jenkins via lwhsu
MFC with: r359438
KTLS uses the embedded header and trailer fields of unmapped
mbufs. This can lead to "silly" buffer lengths, where we have an
mbuf chain that will create a scatter/gather lists with a
regular pattern of 13 bytes followed by 16 bytes between each
adjacent TLS record.
For software ktls we typically wind up with a pattern where we
have several TLS records encrypted, and made ready at once. When
these records are made ready, we can coalesce these silly buffers
in sbready_compress by copying 13b TLS header of the next record
into the 16b TLS trailer of the current record. After doing so,
we now have a small 29 byte chunk between each TLS record.
This marginally increases PCIe bus efficiency. We've seen an
almost 1Gb/s increase in peak throughput on Broadwell based Xeons
running a 100% software TLS workload with Mellanox ConnectX-4
NICs.
Note that this change is ifdef'ed for KTLS, as KTLS is currently
the only user of the hdr/trailer feature of unmapped mbufs, and
peeking into them is expensive, since the ext_pgs struct lives in
separately allocated memory, and may be cold in cache.
This optimization is not applicable to HW ("NIC") TLS, as that
depends on having the entire TLS record described by a single
unmapped mbuf, so we cannot shift parts of the record between
mbufs for HW TLS.
