Documentation: add TLS offload documentation Describe existing kernel TLS offload (added back in Linux 4.19) - the mechanism, the expected behavior and the notable corner cases. This documentation is mostly targeting hardware vendors who want to implement offload, to ensure consistency between implementations. v2: - add emphasis around TLS_SW/TLS_HW/TLS_HW_RECORD; - remove mentions of ongoing work (Boris); - split the flow of data in SW vs. HW cases in TX overview (Boris); - call out which fields are updated by the device and which are filled by the stack (Boris); - move error handling into it's own section (Boris); - add more words about fallback (Boris); - note that checksum validation is required (Alexei); - note that drivers shouldn't pay attention to the TLS device features.
