Subject: [PATCH] mac80211: avoid crashing on invalid band info | ||
|
||
Frequent crashes have been observed on MT7916 based platforms. While the | ||
root of these crashes are currently unknown, they happen when decoding | ||
rate information of connected STAs in AP mode. The rate-information is | ||
associated with a band which is not available on the PHY. | ||
|
||
Check for this condition in order to avoid crashing the whole system. | ||
This patch should be removed once the roout cause has been found and | ||
fixed. | ||
