This is because tx_fwinfo_8190pci points to skb->data
Move the pci_map_single to when completed buffer is ready to be mapped with

Thanks for this.
Commit 95d93e271d920dfda369d4740b1cc1061d41fe7f upstream is also required.
That one does not apply, can you provide a backport for it?
Sorry it is not needed, the bug had appeared since v4.4.
IsACValid had since changed to static function where the math error of
tid < 7 appears.
