right. that keeps things better organised.
include/crypto - holds crypto related header files from bsd
include/netkey - holds netkey related header files

similarly populate src/sys/crypto and src/sys/netkey. after that update
bsd_tcpip/current/cdl/freebsd_net.cdl to control crypto and netkey compilation.
have a look at how cdl_option CYGPKG_NET_FREEBSD_INET6 and
CYGPKG_NET_FREEBSD_SYSCTL have been provided under cdl_component
CYGPKG_NET_FREEBSD_INET . This should give you enough idea on how to add some
new options for crypto and netkey.

if you see under packages/net/ things there are packages available with net. and
if one needs to add a new package there (s)he should follow similar layout and
can use their cdl files as example on how to get cdl files for your additions.

at times it is faster and simpler to learn by examples than reading whole
documentation about cdl and then writing cdl file from scratch.

hope it helps
