From 3e9c8066066621a2c66465d62075bf9e0c87645f Mon Sep 17 00:00:00 2001 From: adrian Date: Sun, 7 Jun 2020 05:08:44 +0000 Subject: [PATCH] [if_ath] Don't update the beacon bits from beacon frames in hostapd mode. This logic is running the beacon receive bits in STA+AP mode on both the STA and AP side. The STA side sees its beacons from the BSS fine; the AP side is seeing other beacons on the same channel but with the BSS node for some odd reason. (I think it's a valid reason, but I currently forget what that valid reason is.) So, just to be cleaner about things, don't run the nexttbtt/etc bits at all if we're in hostap mode. If I ever get mesh working then maybe I'll make sure it works right on mesh+ap and mesh+sta modes. Whilst here, log the VAP i'm being called on to make it clearer what is going on. I may end up adding a VAP dprintf version of this at some point.
