      iwlwifi: pcie: fix support for transmitting SKBs with fraglist

OK.

Please point me to the other one.

This one:

commit cb1a4badf59275eb7221dcec621e8154917eabd1 (tag: wireless-drivers-2019-11-14)

     iwlwifi: pcie: don't consider IV len in A-MSDU

but maybe it's included already?

I just tested (in conductive setup, open network) kernel 5.4, still see
TP significantly lower than what I'd expect... But even in RX?

We added this patch and tested.  I don't think it changed much in our setup,
so maybe we were never hitting the bug for one reason or another.

We see about 675Mbps pktgen upload, and about 1Gbps download.  AP is
/AX and configured for 160Mhz, but AP does not actually transmit at
more than 80Mhz it seems.  I currently have no good way to see what MCS and BW
AX200 is transmitting at.

Thanks,
Ben
