Hello,
I noticed the Marvell Mwifiex wireless driver ended up broken since 
kernel 4.13.0, and it is still the case with 4.14.0 on the Marvell 
ESPRESSOBin, soled by Globalscale Technology. I bought the official 
wireless card from them at the same time as the board. However since 
kernel 4.13.0, wifi as provided via mwifiex_pcie module stopped working. 
I don't have much info on the userspace side, as all that happens is the 
wireless interface is never brought up and stays in 'NO-CARRIER'  state 
according to 'ip a'. However on kernel side, I hope I have some info 
that are more useful ! :) This was logged via systemd-journald with 
debug turned on in mwifiex driver. I am willing to try anything to get 
this kernel working, as it's a lts kernel contrary to 4.12.12 on which 
I'm forced to run for now.

I hope these info will be useful in debugging. I'm new to all these 
kernel stuff, so I may have posted to the wrong place or in a wrong way, 
if so, please let me know.

Thanks in advance
