rtl8180: the network interface is not anymore created

[Fabio Rossi]

I was using successfully the rtl8180 driver but after last git-pull the 
network interface (wlan0) is not anymore created.

I have discovered the problem: there has been a change in mac80211, commit 
3fc7826b95521e40cf53f63437a5fdcc24e54ac4. The problem is that the bit 
NL80211_IFTYPE_STATION is not set during the hardware initialization.

I guess that the problem might be solved inserting the following line of code

    dev->wiphy->interface_modes = BIT(NL80211_IFTYPE_STATION);

somewhere in rtl8180_dev.c but I don't know which is the right point to do so.

Regards,
Fabio

Fabio,

Does this patch fix it for you?

I was with the same problem using linville branch (to test rtl8187se
support). I thought the wlan0 missing was some problem with the
rtl8187se support.

I apply the patch and now I have an wlan0 interface! -:)
I can't see now if the interface is really working, no AP near
to test. But the wlan0 now is created
