 1.11  14-Jun-2020  riastradh ubsec(4): Don't use prev msg's last block as IV for next msg in CBC.

This violates the security contract of the CBC construction, which
requires that the IV be unpredictable in advance; an adaptive adversary
can exploit this to verify plaintext guesses.

XXX Compile-tested only.
 1.10  13-Apr-2015  riastradh Add header guards and necessary includes.
 1.9  19-Apr-2014  bad branches: 1.9.4;
Add support for accelerated AES_CBC in ubsec(4) for BCM5823 and newer.
Update man-page and bump date.
Adjust OpenBSD RCS IDs to reflect roughly the version we are in sync with.
 1.8  18-Apr-2014  bad Rewrite the dmamap handling to allocate and cache the dmamaps beforehand.
Calling bus_dmamap_create/destroy is no longer possible in interrupt context.
Move the dmamaps to the end of struct ubsec_q so the rest of the struct
can be cleared with one call to memset().

As a bonus we get a 25% increase in throughput encrypting 8K blocks.
 1.7  17-Nov-2013  bad branches: 1.7.2;
Add support for BCM5825, and BCM5860, 5861, 5862 from OpenBSD rev 1.143:
Add support for the BCM5825 and the next-generation BCM5860, 5861,
5862 Broadcom CryptoNetX IPSec/SSL Security Processors. The 5825 is a
faster version of the already supported 5823, and the even faster 586x
series is a bit different and needed some more changes.

AES support hasn't been pulled in yet.
 1.6  17-Nov-2013  bad Make ubsec(4) loadable as kmod.
 1.5  13-Jun-2013  tls branches: 1.5.2;
Convert the entropy pool framework from pseudo-callout-driven to
soft interrupt driven operation.

Add a polling mode of operation -- now we can ask hardware random number
generators to top us up just when we need it (bcm2835_rng and amdpm
converted as examples).

Fix a stall noticed with repeated reads from /dev/random while testing.
 1.4  27-Oct-2012  chs split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.3  04-Mar-2007  christos branches: 1.3.76; 1.3.86;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.2  11-Dec-2005  christos branches: 1.2.26;
merge ktrace-lwp.
 1.1  01-Aug-2003  jonathan branches: 1.1.4; 1.1.18;
Preliminary port of merged OpenBSD/FreeBSD ubsec driver for Bluesteel
Networks/Broadcom line of cryptographic accelerators.
