It informs the firmware when connecting to a network. This makes the firmware enable the rate control, which makes the upload faster. It also informs the firmware when disconnecting from a network. In the past this made reconnecting impossible because it was sending the auth on queue 0x7 (TXDESC_QUEUE_VO) instead of queue 0x12 (TXDESC_QUEUE_MGNT): wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 1/3) wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 2/3) wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 3/3) wlp0s20f0u3: authentication with 90:55:de:__:__:__ timed out Probably the firmware disables the unnecessary TX queues when it knows it's disconnected. However, this was fixed in commit edd5747aa12e ("wifi: rtl8xxxu: Fix skb misuse in TX queue selection").
