Discussion
This field originates from NetBSD and is also used like this in Linux. It clashes with ../FCS in header. Not parsed properly by wireshark (it parses FCS-in-header instead.)
The PLCP bit is not present in any systems yet but Linux has a comment waiting for it.
Use bit 0x40 in the flags field to indicate FCS CRC failed.
