Any reason this couldn't be implemented for 64bit targets? It looks like the 2-line changes to ath10k_htt_tx_32 would simply need copying to ath10k_htt_tx_64. I could test this on amd64 with QCA9377, if there are no other impediments.

Here the 64bit target means the chip not the host CPU. If you look at the core.c only WCN3990 has target_64bit set to true. I don't have that specific chip to test.
