Since this strcuture represents the message format used between host and firmware, pls add
__packed annotation even though it may not have any effect in this case.

looks like I missed this in a few other structs as well, at least:
ath12k_htt_tx_pdev_rate_stats_tlv
ath12k_htt_rx_pdev_rate_ext_stats_tlv

perhaps i'll take this as-is and then have another patch that adds __packed to
all _tlv structs that are missing it?

actually let me fix this instance in pending, and we can fix other existing
ones separately

Sounds good, thanks.
