From 7463d3a2db0efea3701aab5eeb310e0d8157aff7 Mon Sep 17 00:00:00 2001 From: Boris Pismenny Date: Wed, 27 Feb 2019 17:38:04 +0200 Subject: tls: Fix write space handling TLS device cannot use the sw context. This patch returns the original tls device write space handler and moves the sw/device specific portions to the relevant files. Also, we remove the write_space call for the tls_sw flow, because it handles partial records in its delayed tx work handler.
