There are still some issues with the checksum offload so better to disable it by default until the issues are resolved. To enable TCP checksum offload for tx and rx paths, use the ethtool as follows: ethtool -K tx on ethtool -K rx on To disable TCP checksum offload, for tx and rx paths, use the ethtool as follows: ethtool -K tx off ethtool -K rx off kvalo: indentation changes Signed-off-by: Rishi Panjwani Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/ath6kl/wmi.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'drivers/net/wireless/ath/ath6kl/wmi.h') diff --git a/drivers/net/wireless/ath/ath6kl/wmi.h b/drivers/net/wireless/ath/ath6kl/wmi.h index 96e3cc10cab2..9f8425b97db7 100644 --- a/drivers/net/wireless/ath/ath6kl/wmi.h +++ b/drivers/net/wireless/ath/ath6kl/wmi.h @@ -257,6 +257,9 @@ static inline u8 wmi_data_hdr_get_if_idx(struct wmi_data_hdr *dhdr) #define WMI_META_VERSION_1 0x01 #define WMI_META_VERSION_2 0x02 +/* Flag to signal to FW to calculate TCP checksum */ +#define WMI_META_V2_FLAG_CSUM_OFFLOAD 0x01 + struct wmi_tx_meta_v1 { /* packet ID to identify the tx request */ u8 pkt_id; -- cgit v1.2.1
