The ath10k_sdio errors look like this: [ 196.822363] ath10k_sdio mmc2:0001:1: failed to transmit packet, dropping: -12 [ 196.830109] ath10k_sdio mmc2:0001:1: failed to submit frame: -12 [ 196.836279] ath10k_sdio mmc2:0001:1: failed to push frame: -12 [ 196.925452] ath10k_sdio mmc2:0001:1: failed to transmit packet, dropping: -12 [ 196.933090] ath10k_sdio mmc2:0001:1: failed to submit frame: -12 [ 196.939334] ath10k_sdio mmc2:0001:1: failed to push frame: -12 I am able to reliably reproduce the issue by sending a lot of data from the i.MX7 board to a host connected via the AP: printf '=%.0s' {1..24000} | nc 192.168.0.2 1234 I was able to narrow the issue down to the mtu. If I set the mtu for the wlan0 device to 1486 instead of 1500, the issue does not happen. The size of frames that I see on Wireshark is exactly 1500 after setting it to 1486." Is this a known issue? Alagu/Erik, Have you ever observed such an issue? Thanks
