Patch 1 fixes a bug where WMI_VDEV_PARAM_BA_MODE was never configured for HE in AP mode. The existing code placed the BA mode configuration inside the he_oper.params check, but mac80211 does not populate he_oper.params for AP mode, so HE AP links never had BA mode set. Patch 2 builds on the fix by enabling 1024-entry BA buffers for EHT capable links. IEEE 802.11be extends the maximum BA buffer size from 256 (HE) to 1024 MPDUs; without this patch, EHT-capable links were limited to 256.
