> FCS with zero is valid or invalid ?

An all-zero "FCS" would neither be a valid FCS nor an invalid FCS; it would not
be an FCS at all, it would be padding added to frames transmitted by the Aruba
hardware and also sent out as ERM packets.

If the "FCS" field were zero, we wouldn't check it, we'd just report it as
padding.

(If they use a radiotap header:

the "frame includes FCS" bit of the Flags field:

    http://www.radiotap.org/defined-fields/Flags

can be used to indicate whether there's an FCS or not.)
