Subject: [PATCH] wifi: ath12k: increase vdev setup timeout
Date:   Fri, 28 Apr 2023 14:40:41 +0530
Message-Id: <20230428091041.20033-1-quic_rgnanase@quicinc.com>
Precedence: bulk

From: Aishwarya R <quic_aisr@quicinc.com>

When vdev start/stop happens, response from firmware is received with delay
and hence there is a timeout before VDEV can be up/down.
Also, with maximum peers connected and when vdev stop occurs, firmware
will take time to clean up all the peers and vap queues.
In such cases as well, vdev start/stop response is sent by firmware with delay.

Increase the vdev setup timeout as recommended by firmware team.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0-02903-QCAHKSWPL_SILICONZ-1
