PATCH 1/1 ath11k: Update tx descriptor search index properly

Tx descriptor search index field should be updated with hw peer id and not by AST Hash. Incorrect search index causes throughput degradation in all the platforms. so updated the search index field with hw peer id, which is a common change applicable for all the platforms.

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01492-QCAHKSWPL_SILICONZ-1

no need of configuring the ast_idx, ast_hash field for non station type. Its recommended by HW/FW team.

Can you add this comment in commit message?

Also could you include the answer to "what conditions you observed the throughput degradation?" in commit message too?

Tx descriptor search index field should be updated with hw peer id and not by AST Hash. Incorrect search index causes throughput degradation in all the platforms. so updated the search index field with hw peer id, which is a common change applicable for all the platforms.

Could you be more details under what conditions you observed the throughput degradation?

Thanks,

Peter
