The key_type_rxrpc key that the AFS fs or userspace passes to AF_RXRPC
indicates the protocol that AF_RXRPC should use. The AFS fs doesn't need to
care how the security actually works and the token is opaque to it.
rxkad registers itself with AF_RXRPC, which maintains a list. The
security_index is the number that appears in the protocol that indicates the
security driver to use.
