The firmware name gives no indication what this file is about (remember
that linux-firmware.git has a lot of files). Please name it properly,
don't just use what is used in by firmware build scripts :) Take into
account also future hw support, all firmware files need to coexist in
the same repository without user invention. In a way the firmware
filename is part of kernel/userspace interface and needs to be stable.

For example, you could use something like "qtnfmac/qsr10g.img" (assuming
qsr10g is the name of chip).

I forgot already, is the firmware image ready for submission to

The driver seems to be quite spammy with info messages:

qtnfmac/cfg80211.c:     pr_info("%s: %sregistered mgmt frame type 0x%x\n", 
qtnfmac/cfg80211.c:     pr_info("QTNF: %s cipher=%x, idx=%u, pairwise=%u\n",

qtnfmac/cfg80211.c:     pr_info("QTNF: %s idx=%u, unicast=%u, multicast=%u\n",

qtnfmac/pcie.c: pr_info("starting download firmware %s...\n", bus->fwname);
qtnfmac/pcie.c:         pr_info("successful init of PCI device %x\n", 
qtnfmac/pcie.c: pr_info("Register Quantenna FullMAC PCIE driver\n");
qtnfmac/pcie.c: pr_info("Unregister Quantenna FullMAC PCIE driver\n");
qtnfmac/trans.c:                        pr_info("%s: interrupted\n", __func__);
qtnfmac/trans.c:        pr_info("%s: skb dropped\n", __func__);

Usualle the preference is that driver is quiet until something goes
wrong. I hope some of these could be debug messages.
