When switching between STA and AP modes, memory allocated for Rx vring leaks
This is because start_ap() allocates Rx vring but stop_ap() do not free it.
Logically, Rx vring is not valid (HW can't use it anymore), so free it in reset()
Also, check double init for Rx vring and bail out with -EINVAL

When setting fragmented skb for Tx, assign skb to the last descriptor
and set number of fragments in the 1-st one
On Tx complete, HW sets "DU" bit in Tx descriptor only for the last
descriptor; so search for it using number of fragments field.
Middle descriptors may have "DU" bit not set by the hardware.

When connection established, as reported by WMI_CONNECT_EVENTID,
4-way handshaking required for the secure connection is not done
yet. It is indicated by another WMI event. Wait for it and only then
allow data traffic. In case of non-secure connection, FW reports
"data port open" immediately after connection.
