2WA is what Ubiquiti calls it. It is needed in UBNT_TYPE in order for
the patched fwupdate.real to match and accept the factory.bin

There are two other 2WA devices supported by the same Ubiquiti
firmware. The 2 in 2WA seems to represent the 2.4GHz band (despite the
Bullet AC being able to use either band).
