The documentation for antenna diversity says:
"The decision of diversity is done at 802.11 preamble. So, for
11G/11B, for every MAC packet hardware will do a decision. But in
11N with aggregation, the decision is made only at the preamble and
all other MPDUs will use the same LNA as the first MPDU."
Make use of rs_firstaggr to avoid needlessly scanning for LNA
changes.
