With threaded NAPI, the rx handler function is no longer bound to the CPU that
fired the interrupt, which significantly helps to spread the workload over
multiple CPUs, especially when multiple devices are using threaded NAPI at the
same time.
Exclude the tx handler from threaded NAPI by using a separate dummy netdev.
The work is small and short-lived enough that it makes more sense to run it in
softirq instead of creating a dedicated thread

When operating two VAP on a MT7610 with encryption (PSK2, SAE, OWE),
only the first one to be created will transmit properly encrypteded
frames.
All subsequently created VAPs will sent out frames with the payload left
unencrypted, breaking multicast traffic (ICMP6 NDP) and potentially
disclosing information to a third party.
Disable GTK offloading and encrypt these frames in software to
circumvent this issue. THis only seems to be necessary on MT7610 chips,
as MT7612 is not affected from our testing.
