Error message on wireless connect after latest netcfg update

Question

The connection works, but I since the latest update from this morning I get the following message when connecting to the wireless
network:
nl80211: 'nl80211' generic netlink not found
This is my connection profile:
CONNECTION='wireless'
DESCRIPTION='A simple WPA encrypted wireless connection'
INTERFACE='wlan0'
SECURITY='wpa'
ESSID='Orac'
KEY='xxxxxxxxxx'
IP='static' # Any other CONNECTION='ethernet' options may be used.
ADDR='192.168.1.3'
GATEWAY='192.168.1.1'
DNS=('192.168.1.1')
What is nl80211 and what would I need it for ?

Gusar's answer is correct, you can remove this error (temporary solution) and marginally speed up connecting to wireless by running this patch:

This worked for me.  Thanks!
