trouble building/loading crypto.ko

[Stefan Krüger <stadtkind2@xxxxxx>]

Hi,

I just tried to build the crypto kernel driver as a module, which failed in
multiple ways:

1) there is no zlib.ko

I fixed this by taking FreeBSDs zlib modules/ Makefile and zlib.c changes,
see http://pastebin.mozilla.org/1467564 for git diff

Next error stopping me from loading crypto.ko was:

link_elf_obj_obj: symbol AES_GMAC_Init undefined

I fixed this by adding "gmac.c" to /usr/src/sys/crypto/Makefile, but now I
get this:

# kldload crypto
cryptosoft0: <software crypto> on motherboard

And I'm pretty stuck on this one :(
