I think this patch is too small. It's good to have small atomic commits
but I think goes overboard.

So you are idea with the status template is that instead clearing
status, you copy it from the previous frame and reuse it? Why do you
want to do it? Performance reasons?
I didn't fully understand your idea here, but I assume patch 9 is
related as I see that you change the CRC flag handling from this:
- if (info->fcs_err)
- status->flag |= RX_FLAG_FAILED_FCS_CRC;
to this:
+ fcs_err = ath10k_htt_rx_has_fcs_err(msdu_head);
+ if (fcs_err)
+ info.rx_status.flag |= RX_FLAG_FAILED_FCS_CRC;
+ else
+ info.rx_status.flag &= ~RX_FLAG_FAILED_FCS_CRC;
I don't really like that clearing the flag part. Can you describe what
is your plan behind this template?
