S1G defines use of NDP Block Ack (BA) for aggregation, requiring negotiation
of NDP ADDBA/DELBA action frames. If the S1G recipient supports HT-immediate
block ack, the sender must send an NDP ADDBA Request indicating it expects
only NDP BlockAck frames for the agreement.
Introduce support for NDP ADDBA and DELBA exchange in mac80211. The
implementation negotiates the BA mechanism during setup based on station
capabilities and driver support (IEEE80211_HW_SUPPORTS_NDP_BLOCKACK).
If negotiation fails due to mismatched expectations, a rejection with status code
WLAN_STATUS_REJECTED_NDP_BLOCK_ACK_SUGGESTED is returned as per IEEE 802.11-2024.
