FE_RESET does not means a frontend reset but is meant to reset the 
interrupt bits of the demodulator. On some chips this is required to 
happen quite often, depending on the error rate.

In the new driver the zigzag scan starts after HZ/2, that's half a 
second. Before we only check the status bits.

see above, in order to clear the interrupt bits on those demodulators 
which reqire this.

maybe we can disable the zigzag on a per-frontend basis.

The zigzag code is currently hacked together, the frequency scan 
bandwidth is hardcoded since nobody tested yet the correct values for 
LNB_DRIFT on DVB_S/C/T. When we know these values we can clean up the code.

I'll check what's happening there, if nothing has to happen the FE_RESET 
frontend ioctl should be empty. Have you checked if it suffices to 
disable the FE_RESET call? if not, could you please check this?

thanks,

Holger
