Commit Message

Manikanta Pubbisetty Sept. 5, 2022, 7:18 a.m. UTC 
Increase TCL data ring size to 2048 for WCN6750. This is
needed to meet 160 MHz TX throughput.

Add a new hw_param to indicate the TX ring size for
individual devices.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00887-QCAMSLSWPLZ-1
