QCA988X firmware version and speed

  I've got some observation about firmware version and speed that I
would like to share.
  I have tp-link archer c5 with 'ath10k_pci 0000:01:00.0: qca988x
hw2.0 target 0x4100016c chip_id 0x043202ff sub 0000:0000' running

  When I use firmware version I get modulation speeds
about twice as large as with other firmware versions. I've also tried and firmware-5.bin_10.2.4-1.0-00033 and one that was
Openwrt/Lede stock before that - all show performance noticeably worse
  In fact if my laptop stands on my desk (some distance away from AP)
and I use I get stable 2 spacial stream reception, if I
use other versions mentioned above I usually get one 1 special stream
as shown by 'iw' command on a client.

  I'm not sure if that observation if helpful or not, but since it
looks like newer FW versions have worse performance I thought I should
share it.

  Please let me know if I can provide any more information.
