Yea, and if the "c" version would ever be "promoted" to be the QCA6174 firmware version in the linux-firmware repo again.  Because as it is right now, I think there is a bunch of QCA6174 hardware out there that broke when the QCA6174 firmware-6.bin in linux-firmware went to WLAN.RM.4.4.1-00140-QCARMSWPZ-1 (and up).  And since most distros pick up recent linux-firmware, most current distros have the broken version.
