Hello,
I have been transitioning from 2.6.37 kernel to 3.6-rc6 and have most things
running that I had previously.
Next hurdle is the Sierra Wireless 8705 card. I have tried the kernel drivers
for this device and the latest from the Sierra Wireless site but both result in
the same. When I try to setup the PDP context, which is needed for the setup
of the wwan0 interface I get the following error;
Going to send : AT!SCACT=1,1
[ 77.037811] sierra_net 1-1.3:1.7: wwan0: Link type unsupported: 0xff
[ 77.044433] sierra_net 1-1.3:1.7: wwan0: Invalid LSI
AT!SCACT=1,1
ERROR
I have had a look in the sierra_net code and the return for Link type
unsupported and for some reason its not configured;
/* Validate the link type */
if ((lsi->link_type != SIERRA_NET_AS_LINK_TYPE_IPv4) &&
(lsi->link_type != SIERRA_NET_AS_LINK_TYPE_IPv6)) {
And then the Invalid LSI is in response again to the device structure not being
configured.
I was hoping someone out there has knowledge about additional components that
might be needed to get this to work, or what might have changed from 2.6.37
that needs implementing in the latest driver ?
I have also searched for other issues and it may be related, when the device is
detected and installed there is a complaint about invalid interface number;
