From 1229df4b313acf15d372caadcbbc62a430cd2697 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Thu, 28 Apr 2022 18:41:40 +0200 Subject: net: mac802154: Fix symbol durations There are two major issues in the logic calculating the symbol durations based on the page/channel: - The page number is used in place of the channel value. - The BIT() macro is missing because we want to check the channel value against a bitmask. Fix these two errors and apologize loudly for this mistake.
