ath11k: Add support for RX decapsulation offload
Add support for rx decapsulation offload by advertising the support to mac80211 during registration. Also ensure the frames have the RX_FLAG_8023 flag set in decap offload frames before passing to mac80211. Since the packets delivered to the driver are in 802.3 format, these can be sent to the network core with minimal processing in mac80211. This helps in releasing some CPU cycles in the host processor and thereby improving the performance. Two exceptions are made before passing decap frames, one is for EAPOL packets since mac80211 8023 fast rx for the sta is set only after authorization, other case is for multicast packets to validate PN in mac80211. In both the cases the decap frames are converted to 80211 frame and sent to mac80211. Ethernet decap can be enabled by using frame_mode modparam: insmod ath11k frame_mode=2 Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.5.0.1-00844-QCAHKSWPL_SILICONZ-1 v2 Co-developed-by: Manikanta Pubbisetty <mpubbise@codeaurora.org> Signed-off-by: Manikanta Pubbisetty <mpubbise@codeaurora.org> Signed-off-by: Sriram R <srirrama@codeaurora.org> Signed-off-by: Jouni Malinen <jouni@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20210721204217.120572-1-jouni@codeaurora.org
