was marked as reserved. According to this standard, reserved fields have to be set
to zero. On the other hand, IEEE 802.15.4-2003 standard requires ignoring
reserved bits upon reception. Thus, there is a contradiction in the standard which
can be interpreted in two ways:
a) If
b) If a device should acknowledge all frames independent of its frame version,
The same holds for PAN coordinators as described below.

AACK_FVN_MODE should be set to 3. However, this can result in conflicts with
co-existing IEEE 802.15.4-2006 standard compliant networks.
