On target ipq40xx the kmod-crypto-ctr package does not seem to work. E.g.

modprobe ctr
failed to find a module named ctr

whereas this works on ramips device I have.

Looking in more detail I can see on the ipq40xx device that:

opkg files kmod-crypto-ctr
Package kmod-crypto-ctr (4.14.131-1) is installed on root and has the following files:
/etc/modules.d/09-crypto-ctr

whereas on the other device:

opkg files kmod-crypto-ctr
Package kmod-crypto-ctr (4.14.95-1) is installed on root and has the following files:
/lib/modules/4.14.95/ctr.ko
/etc/modules.d/09-crypto-ctr

This can also be looked by inspecting the ipk files which do not contain a ko file within the data.tar.gz. I have checked this on build 18.06.4, but it seems to also be a problem on 18.06.3 and snapshot.

Thank you for explanation. That makes sense, but I am unable to find any setting in .config to get support for rfc3686(ctr(aes)) compiled into kernel. Are you able to point me in the right direction?

On a mt76x8 device I see it is part of ctr module (below) so if this is not available as a module for ipq40xx I assume there is another way to enable support?

name : rfc3686(ctr(aes))
driver : rfc3686(ctr(aes-generic))
module : ctr
