213ef6e7c9 tls: Move tls_make_aad to header to allow sharing
move tls_make_aad as it is going to be reused
by the device offload code and rx path.
Remove unused recv parameter.

ff45d820a2 tls: Fix TLS ulp context leak, when TLS_TX setsockopt is not used.
Previously the TLS ulp context would leak if we attached a TLS ulp
to a socket but did not use the TLS_TX setsockopt,
or did use it but it failed.
This patch solves the issue by overriding prot[TLS_BASE_TX].close
and fixing tls_sk_proto_close to work properly
when its called with ctx->tx_conf == TLS_BASE_TX.
This patch also removes ctx->free_resources as we can use ctx->tx_conf
to obtain the relevant information.

Use kzalloc for aead_request allocation as
we don't set all the bits in the request.

3c4d755915 tls: kernel TLS support
Software implementation of transport layer security, implemented using ULP
infrastructure.  tcp proto_ops are replaced with tls equivalents of sendmsg and
sendpage.

Only symmetric crypto is done in the kernel, keys are passed by setsockopt
after the handshake is complete.  All control messages are supported via CMSG
data - the actual symmetric encryption is the same, just the message type needs
to be passed separately.

For user API, please see Documentation patch.

Pieces that can be shared between hw and sw implementation
are in tls_main.c
