In order to efficiently serve web traffic on a NUMA
machine, one must avoid as many NUMA domain crossings as
possible. With SO_REUSEPORT_LB, a number of workers can share a
listen socket. However, even if a worker sets affinity to a core
or set of cores on a NUMA domain, it will receive connections
associated with all NUMA domains in the system. This will lead to
cross-domain traffic when the server writes to the socket or
calls sendfile(), and memory is allocated on the server's local
NUMA node, but transmitted on the NUMA node associated with the
TCP connection. Similarly, when the server reads from the socket,
he will likely be reading memory allocated on the NUMA domain
associated with the TCP connection.
This change provides a new socket ioctl, TCP_REUSPORT_LB_NUMA. A
server can now tell the kernel to filter traffic so that only
incoming connections associated with the desired NUMA domain are
given to the server. (Of course, in the case where there are no
servers sharing the listen socket on some domain, then as a
fallback, traffic will be hashed as normal to all servers sharing
the listen socket regardless of domain). This allows a server to
deal only with traffic that is local to its NUMA domain, and
avoids cross-domain traffic in most cases.
This patch, and a corresponding small patch to nginx to use
TCP_REUSPORT_LB_NUMA allows us to serve 190Gb/s of kTLS encrypted
https media content from dual-socket Xeons with only 13% (as
measured by pcm.x) cross domain traffic on the memory controller.

nids(4) was a clever idea in the early 2000's when the market was
flooded with 10/100 NICs with Windows-only drivers, but that hasn't been
the case for ages and the driver has had no meaningful maintenance in
ages. It only supports Windows-XP era drivers.

Sync serial (T1/E1) interfaces are largely irrelevant today and phk
confirms this driver is unnecessary in review D23928.
This leaves ce(4) and cp(4) in the tree. They're likely not relevant
either, but glebius contacted the manufacturer and those devices are
still available for purchase. At glebius' suggestion leave them in
the tree as long as they do not impose a maintenace burden.

Crypto file descriptors were added in the original OCF import as a way
to provide per-open data (specifically the list of symmetric
sessions). However, this gives a bit of a confusing API where one has
to open /dev/crypto and then invoke an ioctl to obtain a second file
descriptor. This also does not match the API used with /dev/crypto on
other BSDs or with Linux's /dev/crypto driver.
Character devices have gained support for per-open data via cdevpriv
since OCF was imported, so use cdevpriv to simplify the userland API
by permitting ioctls directly on /dev/crypto descriptors.
To provide backwards compatibility, CRIOGET now opens another
/dev/crypto descriptor via kern_openat() rather than dup'ing the
existing file descriptor. This preserves prior semantics in case
CRIOGET is invoked multiple times on a single file descriptor.

This driver provides support for Realtek PCI SD card readers. It attaches
mmc(4) bus on card insertion and detaches it on card removal. It has been
tested with RTS5209, RTS5227, RTS5229, RTS522A, RTS525A and RTL8411B. It
should also work with RTS5249, RTL8402 and RTL8411.
