Hi,

I'm trying to configure a 5.4 box with Quagga to support TCP MD5 Passwords. 
I've achieved this previously with 4.10, but when I try to add the 
following kernel options, 5.4 doesn't like it:

options FAST_IPSEC
options crypto
options TCP_MD5

config gives:
VENUS: unknown option "TCP_MD5"


I have this in /etc/ipsec.conf

add 192.168.1.1 192.168.1.2 tcp 0x1000 -A tcp-md5 "[password]";

setkey -f /etc/ipsec.conf gives:
pfkey_open: Protocol not supported


What is the correct way for enabling TCP MD5 signatures on 5.4?

Thanks,
Regards,
Lee.
