Subject: [PATCH 05/13] wifi: nl80211: Refactor the interface combination limit check
Date: Thu, 28 Mar 2024 12:59:08 +0530 [thread overview]
Message-ID: <20240328072916.1164195-6-quic_periyasa@quicinc.com> (raw)
In-Reply-To: <20240328072916.1164195-1-quic_periyasa@quicinc.com>
From: Vasanthakumar Thiagarajan <quic_vthiagar@quicinc.com>
Move the nl80211 interface combination limit advertisement into a helper
function. This will make the iface combination limit advertisement
functionality more scalable for supporting multiple physical hardware
interface combination.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00188-QCAHKSWPL_SILICONZ-1
