From 07c34cad10ab0ac8b06ede8a7fbc55ecf2efa3e6 Mon Sep 17 00:00:00 2001 From: Sathishkumar Muruganandam Date: Tue, 7 Jan 2025 09:31:39 +0530 Subject: [PATCH] wifi: ath12k: encode max Tx power in scan channel list command Currently, when sending the scan channel list command to the firmware, the maximum Tx power is not encoded in the reg2 member. This omission causes the firmware to be unaware of the host's maximum Tx power, leading to incorrect Tx power derivation at firmware level. To resolve this issue, encode the maximum Tx power in the scan channel list command before sending it to firmware.
