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.

EEPROM blobs for MT7613BE radios start with (little endian) 0x7663,
which is also the PCI device ID for this device. The EEPROM is required
for the radio to work at useful power levels, otherwise only the lowest
power level is available.

- BIP key would only be uploaded correctly initially and corrupted on rekey
