From 731cddce6dd110fb2cdee34eddb48599e7251517 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Tue, 1 Feb 2022 19:06:27 +0100 Subject: net: mac802154: Convert the symbol duration into nanoseconds Tdsym is often given in the spec as pretty small numbers in microseconds and hence was reflected in the code as symbol_duration and was stored as a u8. Actually, for UWB PHYs, the symbol duration is given in nanoseconds and are as precise as picoseconds. In order to handle better these PHYs, change the type of symbol_duration to u32 and store this value in nanoseconds. All the users of this variable are updated in a mechanical way.
