From: Igor Mitsyanko <igor.mitsyanko...@quantenna.com>
A set of per-STA statistics can potentially change quite often.
To ensure backwards and forward compatibility,
modify GET_STA_STATS command format:
- introduce two TLV types
- first TLV is a variable-sized bitmap of statistics values
that are filled by firmware
- second TLV is a structure with statistics itself
Only values specified in first TLV are valid.
