This reduces the CPU cycles spent on host CPU for doing the conversion from 802.11 format to ethernet format and thereby improving the performance of the device. This change was tested on IPQ8074 platform (ath11k driver). In tests where CPUs are fully loaded, this change has improved average CPU usage by nearly 8-10%. Note: Ath11k patch in this patchset depends on PN offload series and the multi reo patchset with the following name. "Support hash based reo destination ring selection" v2: - Cover letter is updated with performance improvement numbers - Disabled tid stats update for decap offload case Manikanta Pubbisetty (1): ath11k: add 802.11 decapsulation offloading support Vasanthakumar Thiagarajan (1): mac80211: add receive path for ethernet frame format drivers/net/wireless/ath/ath11k/core.c | 4 + drivers/net/wireless/ath/ath11k/core.h | 3 + drivers/net/wireless/ath/ath11k/dp_rx.c | 184 ++++++++++++++---------- drivers/net/wireless/ath/ath11k/hal_desc.h | 2 + drivers/net/wireless/ath/ath11k/mac.c | 21 +++ include/net/mac80211.h | 20 +++ net/mac80211/rx.c | 217 ++++++++++++++++++++++++++++- 7 files changed, 371 insertions(+), 80 deletions(-)
