i have an older razer blade 2015 model the QCA6174 is branded as "killer networking" wireless card |
|
hello @Geramy i'm on a acer aspire S13 |
|
hi! Does anyone have the exact models of their cards? Even the FCC IDs stamped on them would be nice. There are a handful of QCA6174 variants out there and they have different data path / command path needs. I've fixed one bug in the RX path that caused a panic on my QCA6174 HW3.2, but there are other NICs out there and other bugs to chase. I'd like to try and fix them all but I will need more NICs to test! Thanks! |

@erikarn just compiled your module (cheating on the MA_OWNED undefined in my case). Here is the dmesg when i load the if_athp after compilation: No interface appears in ifconfig, certainly due to the firmware issue |
|
i just cheated again, adding the new modules and replacing firmware-5 with firmware-6 (which exists not the first) in the code. |

please do throw patches at me, I'm tidying up the tree right now in an
attempt to get it ready to land.
