[linux-dvb] Internet via sat: found a temp solution!

[Göran Lindberg <g.lindberg@mctbrattberg.se>]

Hi!

I have a Nexus-s DVB card ver 2.1 that I use for internet via sat
but I had problems with ARM crashes and duplicate packets when pinging.

However, I found a way to go around these problems until
somebody finds the real error:

In DVB/driver/dvb_net.c I found two pices of code that sets the mac filters:

First set the unicast mac:

   dvb_net_filter_set(dev, &priv->secfilter, mac);


on the next line set a list of multicast mac adresses:

   for (i=1; i<priv->multi_num; i++)
            dvb_net_filter_set(dev, &priv->secfilter,
                               priv->multi_macs[i]);


If I outcomment the first OR second one and recompile then it works, no crashes
or duplicate packets! Have tested for 48 hours now!

Since both ways works it must mean that the card is in promiscuous mode all the
time or else I would not get my data when outcommenting the first unicast
filter. (ifconfig dvb0_0 also shows a constant flow of data all the time)
