For SDIO chip, it is different, its TX complete indication is disabled by default, and it has a tx queue in ath10k, and its tx credit control is enabled, total tx credit is 96, when its credit is not sufficient, then the packets will buffered in the tx queue of ath10k, max packets is TARGET_TLV_NUM_MSDU_DESC_HL which is 1024, for SDIO, when mac80211 call ath10k_flush with set drop flag, maybe it have pending packets in tx queue of ath10k, and if it does not have sufficient tx credit, the packets will stay in queue untill tx credit report from firmware, if it is a noisy environment, tx speed is low and the tx credit report from firmware will delay more time, then the num_pending_tx will remain > 0 untill all packets send to firmware. After the 1st ath10k_flush, mac80211 will call the 2nd ath10k_flush without set drop flag immediately, then it will call to ath10k_mac_wait_tx_complete, and it wait untill num_pending_tx become to 0, in noisy environment, it is esay to wait about near 5 seconds, then it cause the suspend take long time. 1st and 2nd callstack of ath10k_flush [ 303.740427] ath10k_sdio mmc1:0001:1: ath10k_flush
