Hello,

I'd like to try ktls but have found the following:

On AMD64 (stable/13) this option is present in the GENERIC kernel 
of world built about a month ago: stable/13-n244496-618dee60231 
and openssl version is 1.1.1i-freebsd

On ARM64 (stable/13) it's *not* present in a world built earlier 
today from stable/13-n244876-0b45290603b. Here, the openssl version 
is 1.1.1j-freebsd

On another ARM64 (main/14) it *is* present in main-n245445-07564e17620 
built with sources from the 11th March. openssl is 1.1.1j-freebsd here 
as well.

I'd like to have it (ktls) available on the ARM64 
stable/13-n244876-0b45290603b. Is it just a matter of adding the option, 
and then the sysctls become available? Is it "better" with openssl[-devel] 
in ports or openssl in base?

thanks,
