This enables use cases such as software crypto and raw tx injection. This change introduces a new module param 'cryptmode'. cryptmode: 0: Use hardware crypto engine globally with native Wi-Fi mode TX/RX encapsulation to the firmware. This is the default mode. 1: Use sofware crypto engine globally with raw mode TX/RX encapsulation to the firmware. 2: Supports both hardware and software crypto with raw mode TX/RX encapsulation to the firmware. By default hardware crypto engine is used. To use software crypto in this mode, set the per ath10k_vif 'nohwcrypt' flag value to True.* *) The patch for setting vif specific 'nohwcrypt' flag when cryptmode=2 would be a separate patch to mac80211. Possible use case examples: - Use software crypto engine in mac80211. (cryptmode=1) - Support inject raw unencrypted frame on monitor interface and use hardware crypto to encrypt the injected Tx frames. (cryptmode=2) - Support receive raw hardware decrypted frame with encryption header on monitor interface. (cryptmode=2) - Support hybrid local & split MAC mode to support tunneling protocols such as CAPWAP: Use hardware crypto for BSS in local mode, and bypass hardware crypto for BSS in split MAC mode. (cryptmode=2, ath10k_vif nohwcrypt=0 for local mode, =1 for split MAC mode) Testing: Used QCA988x hw 2.0 with firmware-4.bin_10.2.4.48 with backports-20150424. All test case tested** with hostapd in both WPA2-PSK-TKIP (11g) and WPA2-PSK-CCMP(11n/ac). Verified ping and http to google.com works. **) Need to skip ATH10K_FW_FEATURE_RAW_MODE_SUPPORT check in core.c to test firmware. After all, none of the existing QCA official firmware exports that firmware bit yet. Test Case cryptmode value tested --------------------------------------------- ---------------------- 1. ath10k hardware crypto can encrypt/decrypt 0: PASS data frames when hostapd config the BSS in 1: Not applicable. WPA2-PSK-TKIP and WPA2-PSK-CCMP modes. 2: PASS 2. mac80211 software crypto can encrypt/decrypt 0: Not applicable data frames when hostapd config the BSS in 1: PASS WPA2-PSK-TKIP and WPA2-PSK-CCMP modes. 2: PASS, when vif nohwcrypt=1 3. Monitor interface Tx: User application can 0: Not applicable inject unencrypted raw Tx frames to monitor 1: PASS (mac80211) interface for mac80211 or hardware to encrypt 2: PASS (hardware) the frames. 4. Monitor interface Rx: mac80211 software crypto 0: Not applicable engine can decrypt received TKIP/CCMP frames. 1: PASS User application see decrypted frames. 2: PASS, when vif nohwcrypt=1 5. CAPWAP-like local and split MAC datapath 0: Not applicable tunneling: Setup BSS1=Local MAC mode on wlan0, 1: Not applicable BSS2=Split MAC mode on wlan0_monitor interface. 2: PASS Test BSS1 data frames can be encrypted and decrypted by ath10k hardware crypto engine while BSS2 data frames can skip both hardware & kernel mac80211 crypto engines via monitor interface to the user application fot tunneling.
