Subject: P2P: Remove GO handling in avoid frequency event
X-Git-Tag: hostap_2_5~199
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a7160f7ede509bf1bd4b346899711e25320f13db;p=thirdparty%2Fhostap.git

P2P: Remove GO handling in avoid frequency event

Remove the code that considers removing GOs from their current
channel due to frequency interference, as this is already handled
as part of the P2P channels update.
