Subject: [PATCH AUTOSEL 6.6 286/294] wifi: ath12k: fix ath12k_hal_tx_cmd_ext_desc_setup() info1 override

From: Nicolas Escande <nico.escande@...il.com>

[ Upstream commit df11edfba49e5fb69f4c9e7cb76082b89c417f78 ]

Since inception there is an obvious typo laying around in
ath12k_hal_tx_cmd_ext_desc_setup(). Instead of initializing + adding
flags to tcl_ext_cmd->info1, we initialize + override. This will be needed
in the future to make broadcast frames work with ethernet encapsulation.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
