This series addresses two related issues with Block Acknowledgement (BA)
configuration for HE and EHT capable links.

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.
