This patch adds support for new FullMAC WiFi driver for Quantenna
QSR10G chipsets.
QSR10G is Quantenna's 8x8, 160M, 11ac offering.
QSR10G supports 2 simultaneous WMACs- one 5G and one 2G. 5G WMAC
supports 160M, 8x8 configuration.
FW supports 8 concurrent virtual interfaces on each WMAC.
Patch introduces 2 new drivers- qtnfmac.ko for interfacing with
kernel/cfg80211 and qtnfmac_pcie.ko for PCIe bus interface.

Nice to see this one, will you also provide a pearl-linux.lzma.img as
required for the firmware? What about cards in embedded devices, might
they require a uboot as well? Since requesting uboot seems to be
specifically supported by the card/firmware interface.

You will need to remove this footer to be taken seriously, as
confidential information would be not GPL compatible, and "may
contain" means it is too risky to accept that.

Yeah, I'm not going to take (or even look) patches with such
disclaimers. So please resend so that we can start the review.

Kalle, Jonas,
we will resend the patch without disclaimer, sorry for inconvenience.

Hi Jonas,
we will provide firmware, but we're not sure at which point it should be
done: addressing any review comments for driver may affect firmware
itself, probably the best time to provide firmware would be after new
driver is accepted and merged?
Uboot is currently not needed: right now device only supports booting
with uboot binary stored in internal flash memory, we do not transfer it
from host over PCIe.

I would prefer to see the firmware images publically available before
the driver gets applied. What if you send the firmware patches as RFC
only to linux-wireless? That way linux-firmware.git maintainers won't
apply them, hopefully. And mention in the commit log that this is just
for testing purposes, not to be applied.

Kalle, sure, we will send firmware binary as an RFC to linux-wireless
while patch itself is in review.
