ath10k: add a condition to fill the LDPC capability correctly (ff488d0e) · Commits · 戴 / test

The firmware advertises the LDPC support information for HT in HT capability info in the wmi service ready event. To provide granularity, firmware now advertises WMI_HT_CAP_RX_LDPC and WMI_HT_CAP_TX_LDPC separately. To support LDPC, host should also check for WMI_HT_CAP_RX_LDPC and WMI_HT_CAP_TX_LDPC in HT capabilities. Add a condition to existing logic in host to know whether firmware supports LDPC or not. Tested HW: WCN3990 Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1, WLAN.HL.2.0-01617-QCAHLSWMTPLZ-1 Signed-off-by:
