	Enable kernel support for TLS protocol. This allows symmetric
	encryption handling of the TLS protocol to be done in-kernel.

	If unsure, say N.
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.
