Subject: [PATCH net-next v3 0/7] In-kernel support for the TLS Alert protocol

IMO the kernel doesn't need user space (ie, tlshd) to handle the TLS
Alert protocol. Instead, a set of small helper functions can be used
to handle sending and receiving TLS Alerts for in-kernel TLS
consumers.


Changes since v2:
* Simplify header dependencies

Changes since v1:
* Address review comments from Hannes
