Up from 2020.4 build it's not posible to load some extra kernel modules on ASUS RT-AC66 B1

Hi.

Currently I’m using “freshtomato-RT-AC66U_B1-ARM_NG-2021.2-VPN-64K.trx”

Then I try to add some extra modules, for example, “insmod /opt/extras/ipsec/af_key” I’m geting this response:

insmod: can't insert '/opt/extras/ipsec/af_key.ko': Invalid argument .

dmesg shows a lot of records like this:

af_key: Unknown symbol xfrm_state_update (err -22)
af_key: disagrees about version of symbol xfrm_policy_insert
af_key: Unknown symbol xfrm_policy_insert (err -22)
af_key: disagrees about version of symbol xfrm_init_state
af_key: Unknown symbol xfrm_init_state (err -22)
af_key: disagrees about version of symbol xfrm_find_acq_byseq
af_key: Unknown symbol xfrm_find_acq_byseq (err -22)
af_key: disagrees about version of symbol sock_init_data
af_key: Unknown symbol sock_init_data (err -22)
af_key: disagrees about version of symbol xfrm_state_delete
af_key: Unknown symbol xfrm_state_delete (err -22)
af_key: disagrees about version of symbol xfrm_state_walk
af_key: Unknown symbol xfrm_state_walk (err -22)

Same with a lot of other modules from /extra/ipsec folder.

For me it looks like some version mismatch between kernel and extra-package files happened .

Can anyone clarify the situation?
