[PATCH ath-next 2/2] wifi: ath12k: Increase RXDMA buffer ring size for default memory profile

[Aaradhana Sahu]

From: Pavankumar Nandeshwar <pavankumar.nandeshwar at oss.qualcomm.com>

The default RXDMA buffer ring size of 4096 entries can become a
bottleneck under high RX traffic load, resulting in reduced receive
throughput due to limited buffer availability.

Increase the RXDMA buffer ring size to 8192 entries for the default
memory profile to provide additional RX buffering and improve RX packet
processing efficiency.

This increases memory consumption by approximately 9-10 MiB and improves
RX throughput by ~20% with the default memory profile
(ATH12K_QMI_MEMORY_MODE_DEFAULT).

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c7-00108-QCAHMTSWPL_V1.0_V2.0_SILICONZ_UPSTREAM-3
Tested-on: QCC2072 hw1.0 PCI WLAN.COL.1.0.c2-00074-QCACOLSWPL_V1_TO_SILICONZ-1
