I was just editing my proposal for that, and it occurred to me that now
we have only one a-MPDU bit here in the MCS field, and technically
non-MCS frames can also be aggregated, so it never really belonged here
anyway.

Therefore, what do you think of these changes:

1) remove the a-MPDU bit from the MCS field completely

2) add a new a-MPDU field with the following definition:

bit number: 20
structure: u8 flags_idx
required alignment: 1

The presence of this field indicates that the frame was received as part
of an a-MPDU. The format of the flags_idx field is as follows:

bit 7:     index field valid, otherwise the index isn't known
bits 6-0:  index field -- zero-based index of
           this MPDU within the a-MPDU

(technically, only bits 5-0 are required for the index, because it can
only go up to 63)
