Subject: [PATCH wireless 0/4] wifi: mt76: fix RCPI chain 3 mask in sta_poll RSSI extraction
Date: Mon, 6 Apr 2026 19:47:35 -0400 [thread overview]
Message-ID: <20260406234739.29926-1-joshuaklinesmith@gmail.com> (raw)
The fourth receive chain RCPI extraction in sta_poll uses
GENMASK(31, 14), an 18-bit mask spanning bits 14-31. It should
be GENMASK(31, 24), an 8-bit mask for the fourth byte, consistent
with the other three chains and with the RCPI3 definitions used
elsewhere in the driver.
On devices with fewer than 4 antenna chains the corrupted value
is masked out by antenna_mask. On 4-chain devices this produces
incorrect ACK signal strength readings.
