Currently IPsec uses capabilities from crypto module to report supported
key lengths. Crypto capabilities also contain additional data (like
digest length, IV len, AAD len, etc. However this data is not relevant
for IPsec, as most of such variables are fixed by protocol standards.
To simplify application code provide copies of cipher and auth
capabilities structures containing only relevant data (key lengths).
