The CFO (central frequency offset) is very important to yeild good UL-OFDMA
performance. To track CFO accurately, adjust CFO in shorter period of time.
Since this is only needed by UL-OFDMA, we use trigger frames as a clue.

v2: remove ULL suffix from MASK definition

Eric Huang (1):
  rtw89: add new state to CFO state machine for UL-OFDMA

Po Hao Huang (2):
  ieee80211: add trigger frame definition
  rtw89: 8852c: add trigger frame counter
