Not Much, i could see the below pattern repeating

So We move from NONE to AUTH and then AUTH to NONE. iwlwifi_dev_tx is
transmistting 90 bytes packets
but auth request is only 43 bytes, could that be association request??
If yes where is that getting dropped.

So my guess is that we are sending the association request (CMD_TX),
but its never seen OTA, its lost some where in between.
Ball goes to the FW :-).
