Re: [leaf-wisp] netcs2 essid problem

The bug is a clash in interface naming.

When the system brings the fixed wireless interface up, it gets 
assigned name "netcs0". That conflicts with "netcs0" which should be 
assigned to PCMCIA socket #0.

After some thought it seems that the only proper fix (actually a hack) 
is to add the following after line 17 in /etc/network/wireless-start:

SOCKET=`expr $SOCKET + 1`

This will shift naming of all PCMCIA interfaces by +1 and therefore 
there will be no clash with netcs0.

I cannot think of a proper automatic fix right now... I don't want to 
scrap the interface name<->socket number binding scheme altogether as 
it may lead to unpredictable mapping between interface names and 
physical cards, as there is no guarantee that all interfaces will be 
discovered in the same order each time.
