From: Dinesh Karthikeyan <quic_dinek@xxxxxxxxxxx>
Add support to request uplink MUMIMO trigger stats from firmware
through HTT stats type 27. These stats give information about
bandwidth, RSSI of signal received, dB mean of pilots received,
etc., of all users.
Note: MCC firmware version WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
does not support tags HTT_STATS_RX_PDEV_UL_TRIG_STATS_TAG(94) and
HTT_STATS_RX_PDEV_UL_OFDMA_USER_STATS_TAG(95), currently.
Sample output:
