ath10k: add a condition to fill the LDPC capability correctly
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: Surabhi Vishnoi <svishnoi@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
