From afa147c45ad35a036600bc737b6b39cf1d33ccd4 Mon Sep 17 00:00:00 2001 From: Andre Heider Date: Wed, 23 Nov 2022 15:21:57 +0100 Subject: nl80211: add "mhz" and "band" to iwinfo_scanlist_entry Providing the channel alone isn't clear as there're overlapping channels on e.g. band 2 and 6. Note: This changes the ABI.
