      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?

It is not in 5.2, I'll add it to my tree.


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?

Please let us know what you actually see and expect and if what mode
you are using (VHT, HE, 160Mhz, 2x2 vs 1x1, etc).

Conductive test is not actually isolation from your environment (cables leak, especially
SMA pigtails, as do radio cards and so forth, and they leak both in and out), so
you will need a real shield chamber if you want to have repeatable
testing.  And, make sure you have 30db of attenuation or so inserted
if you are doing cabled setup, otherwise signal is too hot for the chips.

Thanks,
Ben
