dmesg > dmesg.txt

Description of problem:
I've got a late 2015 macbook pro with the fedora 25 beta installed. Whilst the wireless will occasionally work fine for a couple of hours or so, usually I get one of the following two symptoms -

* ~70% packet loss, making the link totally unusable
* Not connecting at all - NetworkManager is repeatedly asking for my WLAN password.

I'm using the built-in brcmfmac driver - I had even less joy with the broadcom proprietary wl driver, but that's another story.

Version-Release number of selected component (if applicable):

```
[kj@kjs-macbook-pro ~]$ uname -a
Linux kjs-macbook-pro 4.8.6-300.fc25.x86_64 #1 SMP Tue Nov 1 12:36:38 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
```

How reproducible:
Pretty much guaranteed


Steps to Reproduce:
1. Try and connect to WLAN network on a 2015 Macbook Pro
2. Enter network password
3.

Actual results:
.... get asked for your network password again by NetworkManager

Expected results:
Connect to the network!

Additional info:
I've attached dmesg, which looks like it has some relevant stuff in it.

Note the error about 'Direct firmware load for brcm/brcmfmac43602-pcie.txt failed with error -2' - I don't have such a file on my system, but I do have /lib/firmware/brcm/brcmfmac43602-pcie.bin. When I tried copying the latter to the former I got kernel panics when modprobing the brcmfmac module.

Man I wish they just shipped an Intel chip in these computers instead of this broadcom junk...
