From 63dde087796bfcd730508b069ebae7c79b7cebe8 Mon Sep 17 00:00:00 2001 From: Dimitri Staessens Date: Sat, 26 Mar 2022 09:39:49 +0100 Subject: lib: Refactor reading packet from rbuff Reading packets from the rbuff and checking their validity (non-zero size, pass crc check, pass decryption) is now extracted into a function. Also adds a function to get the length of an sdu_du_buff instead of subtracting the tail and head pointers.
