[Airo-linux-gen80211] Problem faced in writing onto skb->data (packet)

[Vishal B. <vis...@ya...>]

Hi all!

I am trying to pass on the signal strength info in the
packet so that a sniffer can be used at a higher level
and extract the signal strength info.. In the function


static void airo_interrupt (int irq, void*dev_id,
struct pt_regs *regs) {

I am adding the three commented out lines to the
code.. 

 } else {
            bap_setup (apriv, fid, 0x38, BAP0);
            bap_read (apriv, buffer,len +
hdrlen,BAP0);
         }
           OUT4500( apriv, EVACK, EV_RX);
                                         
//skb->data[24]=hdr.rssi[0];
                               
//skb->data[25]=0x100-apriv->rssi[hdr.rssi[1]].rssidBm;
                              //skb->data[26]=0x36;
//just to check if it is really changing the values

#ifdef WIRELESS_SPY

The problem is that on one of the machines(the
powerful machine ... P4 2.4 Ghz), it is working
perfectly..
whereas when i try to install the module on the other
old machines, with the same kernel and same
pcmcia-cs-3.2.3, with the airo files taken from 

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/airo-linux/airo-linux/kernel/airo.c?rev=1.34

it compiles perfectly, and even loads on 'modprobe
airo', but when i try to bring the interface up by
'ifconfig eth1 up' , I get the error

eth1: unknown interface: No such device

and no errors are thrown up by the kernel in
/var/log/messages. 

I would really appreciate any help in this regard... 

Thanks,
Vishal
