In order to receive other BSS entries in mesh mode, Monitor vdev is created whenever filter flag is set with OTHER_BSS. Recently it is root caused that setting promisc filter for Mesh interface is causing performance and stability issues. To fix this issue, firmware will configure appropriate rxfilters by default for mesh vdev during vdev creation. This change fixes monitor vdev creation based on firmware IE Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> --- drivers/net/wireless/ath/ath10k/core.c | 1 + drivers/net/wireless/ath/ath10k/core.h | 7 +++++++ drivers/net/wireless/ath/ath10k/mac.c | 4 +++- 3 files changed, 11 insertions(+), 1 deletion(-)
