This learning can't be disabled by default in FW since it breaks backward compatibility. Since ath10k uses mac80211 based 4addr mode, source port learning done in 10.4 FW is redundant and also causes issues when 3addr frames are transmitted/received for a 4addr station. One such visible functional impact is when GTK rekey frame from hostapd based AP to 4addr STA is dropped in AP's 10.4 FW. This is since GTK rekey EAPOL frame is 3addr frame on AP interface and STA enabled with 4addr is already allowed for receiving 3addr EAPOL frames. Source port learning implementation in 10.4 FW drops this 3addr GTK rekey frame in AP destinated for 4addr STA causing disassociation and re-association for every GTK rekey session. GTK rekey issue is not seen when learning is disabled in FW. To prevent such issues without breaking backward compatibility, FW advertises new service bit making the source port learning configurable and this learning is being currently disabled during ath10k vdev creation. * Tested HW: QCA9984 * Tested FW: 10.4-3.6.0.1-00004 Signed-off-by: Sathishkumar Muruganandam --- Changes in v2: * Added the missing VDEV param assignments to 10.4 and 10.2.4 * Updated latest FW version drivers/net/wireless/ath/ath10k/mac.c | 11 +++++++++++ drivers/net/wireless/ath/ath10k/wmi.c | 4 ++++ drivers/net/wireless/ath/ath10k/wmi.h | 21 ++++++++++++++++++++- 3 files changed, 35 insertions(+), 1 deletion(-) diff --git a/drivers/net/wireless/ath/ath10k/mac.c b/drivers/net/wireless/ath/ath10k/mac.c index c5130fa264eb..aac4d842d504 100644 --- a/drivers/net/wireless/ath/ath10k/mac.c +++ b/drivers/net/wireless/ath/ath10k/mac.c @@ -5154,6 +5154,17 @@ static int ath10k_add_interface(struct ieee80211_hw *hw, goto err;
