The firmware is +able to do this operation for us, so enable encapsulation offloading for +AP and Sta interface types to improve overall system performance. + +The driver is almost ready for encapsulation offloading support. There +are only a few places where the driver assumes the frame format is IEEE +802.11 that need to be fixed. + +Encapsulation offloading is currently disabled by default and the driver +utilizes mac80211 encapsulation support. To activate offloading, the +frame_mode=2 parameter should be passed during module loading. + +On a QCA9563+QCA9888-based access point in bridged mode, encapsulation +offloading increases TCP 16-streams DL throughput from 365 to 396 mbps +(+8%) and UDP DL throughput from 436 to 483 mbps (+11%). + +Tested-on: QCA9888 hw2.0 PCI 10.4-3.9.0.2-00131 +Tested-on: QCA6174 hw3.2 PCI WLAN.RM.4.4.1-00157-QCARMSWPZ-1 +Signed-off-by: Sergey Ryazanov +Tested-by: Oldřich Jedlička # TP-Link Archer C7 v4 & v5 (QCA9563 + QCA9880) +Tested-by: Edward Matijevic # TP-Link Archer C2600 (IPQ8064 + QCA9980 10.4.1.00030-1) +Tested-by: Edward Matijevic # QCA9377 PCI in Sta mode +Tested-by: Zhijun You # NETGEAR R7800 (QCA9984 10.4-3.9.0.2-00159) +Signed-off-by: Kalle Valo +Link: https://lore.kernel.org/r/20220516032519.29831-5-ryazanov.s.a@gmail.com +--- + drivers/net/wireless/ath/ath10k/core.c | 2 +- + drivers/net/wireless/ath/ath10k/mac.c | 67 +++++++++++++++++++++++++++------- + 2 files changed, 55 insertions(+), 14 deletions(-) + +--- a/drivers/net/wireless/ath/ath10k/core.c ++++ b/drivers/net/wireless/ath/ath10k/core.c +@@ -54,7 +54,7 @@ MODULE_PARM_DESC(uart_print, "Uart targe + MODULE_PARM_DESC(skip_otp, "Skip otp failure for calibration in testmode"); + MODULE_PARM_DESC(cryptmode, "Crypto mode: 0-hardware, 1-software"); + MODULE_PARM_DESC(frame_mode, +- "Datapath frame mode (0: raw, 1: native wifi (default))"); ++ "Datapath frame mode (0: raw, 1: native wifi (default), 2: ethernet)"); + MODULE_PARM_DESC(coredump_mask, "Bitfield of what to include in firmware crash file"); + MODULE_PARM_DESC(fw_diag_log, "Diag based fw log debugging"); + +--- a/drivers/net/wireless/ath/ath10k/mac.c ++++ b/drivers/net/wireless/ath/ath10k/mac.c +@@ -3710,6 +3710,9 @@ ath10k_mac_tx_h_get_txmode(struct ath10k + const struct ath10k_skb_cb *skb_cb = ATH10K_SKB_CB(skb); + __le16 fc = hdr->frame_control; + ++ if (IEEE80211_SKB_CB(skb)->flags & IEEE80211_TX_CTL_HW_80211_ENCAP) ++ return ATH10K_HW_TXRX_ETHERNET; ++ + if (!vif || vif->type == NL80211_IFTYPE_MONITOR) + return ATH10K_HW_TXRX_RAW; + +@@ -3870,6 +3873,12 @@ static void ath10k_mac_tx_h_fill_cb(stru + bool noack = false; + + cb->flags = 0; ++ ++ if (info->flags & IEEE80211_TX_CTL_HW_80211_ENCAP) { ++ cb->flags |= ATH10K_SKB_F_QOS; /* Assume data frames are QoS */ ++ goto finish_cb_fill; ++ } ++ + if (!ath10k_tx_h_use_hwcrypto(vif, skb)) + cb->flags |= ATH10K_SKB_F_NO_HWCRYPT; + +@@ -3908,6 +3917,7 @@ static void ath10k_mac_tx_h_fill_cb(stru + cb->flags |= ATH10K_SKB_F_RAW_TX; + } + ++finish_cb_fill: + cb->vif = vif; + cb->txq = txq; + cb->airtime_est = airtime; +@@ -4031,7 +4041,11 @@ static int ath10k_mac_tx(struct ath10k * + ath10k_tx_h_seq_no(vif, skb); + break; + case ATH10K_HW_TXRX_ETHERNET: +- ath10k_tx_h_8023(skb); ++ /* Convert 802.11->802.3 header only if the frame was erlier ++ * encapsulated to 802.11 by mac80211.
