: on the topic of IPSEC/Crypto/Cryptodev (soft), is anyone interested in
: testing pr- 120270 (feature request
: http://www.freebsd.org/cgi/query-pr.cgi?pr=120270 ) - because there are
: still some features missing like AES-192/256 hardware support

There seems to be a number of changes swizzled together in the diff in
this PR.  Things like:

 #if defined(__OpenBSD__) || defined(__FreeBSD__)
-        ENGINE_load_cryptodev();
+        ENGINE_load_cryptodev();
and then later

 void *ENGINE_get_static_state(void);
-#if defined(__OpenBSD__) || defined(__FreeBSD__)
+#if defined(__OpenBSD__) || defined(__FreeBSD__) || defined(HAVE_CRYPTODEV)
 void ENGINE_setup_bsd_cryptodev(void);

and the like.
