Subject: [PATCH 04/10] rtlwifi: unlink bss when un-association
Date: Wed, 10 Jan 2018 13:19:56 +0800 [thread overview]
Message-ID: <20180110052002.9544-5-pkshih@realtek.com> (raw)
In-Reply-To: <20180110052002.9544-1-pkshih@realtek.com>
From: Tsang-Shian Lin <thlin@realtek.com>
When AP change bandwidth setting from 20M to 40M, STA may use old 20M AP
information to association with AP. Driver unlink bss in the
.bss_info_changed of ieee80211_ops to make sure that later scan can get
correct AP bandwidth capability.
