How to Enable support for IPsec deprecated algorithms: 3DES, MD5-HMAC

Hi, i am trying to move my gateway from FreeBSD 11.0 to FreeBSD 14.0 to use
newly added ipfw table lookup for mac addresses (https://reviews.freebsd.org/D35103)

Also I have too many IPSec connections between fortigate, cisco etc.
And their operators use only 3DES algorithms and they have no intention to change it for me.
So, now i have to enable 3DES support for FreeBSD 14.0 .

To add 3DES support again i changed some files shown below.
I am not sure what i did any help welcomes.

i restored below files:

Compiled New Kernel with this extra options:

# OWNKERNv1
include GENERICident OWNKERNv1

options IPFIREWALL
options DUMMYNET
options IPFIREWALL_DEFAULT_TO_ACCEPT
options IPDIVERT
options IPSEC
options IPSEC_SUPPORT
device crypto

cd /usr/src
make -j$(sysctl -n hw.ncpu) buildkernel KERNCONF=OWNKERNv1

But When i try to compile new kernel it gets too many errors.
any help will be appreciated at this point..
