Currently, the mac80211 layer handles construction and parsing of 802.11 headers during packet transmission and reception. Offloading encapsulation and decapsulation to hardware can significantly enhance performance. This can be achieved by having the driver advertise hardware support to mac80211 to bypass 802.11 header processing Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00217-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 Signed-off-by: Nithyanantham Paramasivam <nithyanantham.paramasivam@oss.qualcomm.com> --- drivers/net/wireless/ath/ath12k/mac.c | 2 ++ 1 file changed, 2 insertions(+)
