pf by default does not do per-table address accounting unless the
"counters" keyword is specified in the corresponding pf.conf table
definition. Yet, we always allocate 12 per-CPU counters per table. For
large tables this carries a lot of overhead, so only allocate counters
when they will actually be used.
A further enhancement might be to use a dedicated UMA zone to allocate
counter arrays for table entries, since close to half of the structure
size comes from counter pointers. A related issue is the cost of
zeroing counters, since counter_u64_zero() calls smp_rendezvous() on
some architectures.

BINUTILS is needed only for ports, and will be disabled once the failing
ports are addressed (likely by growing a binutils dependency).
BINUTILS_BOOTSTRAP is needed only on amd64, for skein_block_asm.s. There
is no need to enable it on i386.
This will all be removed before FreeBSD 13.0.
With the removal of in-tree consumers of DES, Triple DES, and
MD5-HMAC, the only algorithm this driver still supports is SHA1-HMAC.
This is not very useful as a standalone algorithm (IPsec AH-only with
SHA1 would be the only user).
This driver has also not been kept up to date with the original driver
in OpenBSD which supports a few more cards and AES-CBC on newer cards.
The newest card currently supported by this driver was released in
2005.

Save and restore (also known as suspend and resume) permits a snapshot
to be taken of a guest's state that can later be resumed. In the
current implementation, bhyve(8) creates a UNIX domain socket that is
used by bhyvectl(8) to send a request to save a snapshot (and
optionally exit after the snapshot has been taken). A snapshot
currently consists of two files: the first holds a copy of guest RAM,
and the second file holds other guest state such as vCPU register
values and device model state.
To resume a guest, bhyve(8) must be started with a matching pair of
command line arguments to instantiate the same set of device models as
well as a pointer to the saved snapshot.
While the current implementation is useful for several uses cases, it
has a few limitations. The file format for saving the guest state is
tied to the ABI of internal bhyve structures and is not
self-describing (in that it does not communicate the set of device
models present in the system). In addition, the state saved for some
device models closely matches the internal data structures which might
prove a challenge for compatibility of snapshot files across a range
of bhyve versions. The file format also does not currently support
versioning of individual chunks of state. As a result, the current
file format is not a fixed binary format and future revisions to save
and restore will break binary compatiblity of snapshot files. The
goal is to move to a more flexible format that adds versioning,
etc. and at that point to commit to providing a reasonable level of
compatibility. As a result, the current implementation is not enabled
by default. It can be enabled via the WITH_BHYVE_SNAPSHOT=yes option
for userland builds, and the kernel option BHYVE_SHAPSHOT.

- Add a new TCP_RXTLS_ENABLE socket option to set the encryption and
authentication algorithms and keys as well as the initial sequence
number.
- When reading from a socket using KTLS receive, applications must use
recvmsg(). Each successful call to recvmsg() will return a single
TLS record. A new TCP control message, TLS_GET_RECORD, will contain
the TLS record header of the decrypted record. The regular message
buffer passed to recvmsg() will receive the decrypted payload. This
is similar to the interface used by Linux's KTLS RX except that
Linux does not return the full TLS header in the control message.
- Add plumbing to the TOE KTLS interface to request either transmit
or receive KTLS sessions.
- When a socket is using receive KTLS, redirect reads from
soreceive_stream() into soreceive_generic().
- Note that this interface is currently only defined for TLS 1.1 and
1.2, though I believe we will be able to reuse the same interface
and structures for 1.3.
