Commit Message

From: Dinesh Karthikeyan <quic_dinek@quicinc.com>

Add support to request Address Search Table(AST) entries stats
from firmware through HTT stats type 41. These stats give AST entries
related information such as software peer id, MAC address, pdev id,
vdev, id, next hop, etc.

Sample output:
-------------
echo 41 > /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats_type
cat /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats
HTT_AST_ENTRY_TLV:
ast_index = 10
mac_addr = 00:00:00:01:00:00
sw_peer_id = 0
pdev_id = 3
vdev_id = 255
next_hop = 0
mcast = 0
monitor_direct = 0
mesh_sta = 0
mec = 0
intra_bss = 0

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
