From: Johannes Berg <[email protected]> The current code assigns the reference, and then goes to increment it if the toggle bit has changed. That way, we get
Toggle 0 0 0 0 1 1 1 1 ID 1 1 1 1 1 2 2 2 Fix that by assigning the post-toggle ID to get Toggle 0 0 0 0 1 1 1 1 ID 1 1 1 1 2 2 2 2 Reported-by: Danny Alexander <[email protected]> Signed-off-by: Johannes Berg <[email protected]> Fixes: fbe4112791b8 ("iwlwifi: mvm: update mpdu metadata API") Signed-off-by: Luca Coelho <[email protected]> --- drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c b/drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c index 9342f61b702e..120e3f2d21aa 100644 --- a/drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c +++ b/drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c @@ -1438,12 +1438,12 @@ void iwl_mvm_rx_mpdu_mq(struct iwl_mvm *mvm, struct napi_struct *napi, bool toggle_bit = phy_info & IWL_RX_MPDU_PHY_AMPDU_TOGGLE; rx_status->flag |= RX_FLAG_AMPDU_DETAILS; - rx_status->ampdu_reference = mvm->ampdu_ref; /* toggle is switched whenever new aggregation starts */ if (toggle_bit != mvm->ampdu_toggle) { mvm->ampdu_ref++; mvm->ampdu_toggle = toggle_bit; } + rx_status->ampdu_reference = mvm->ampdu_ref; } rcu_read_lock(); -- 2.20.1
