the attached patch (against r37341) checks the address of the Configuration
Option Register that is used for switching a PC-Card in DVB-CI mode.
The address must be <= 0xffe. In my pcap definition
(http://www.kaiser.cx/pcap-dvbci.html), I defined 0xffff as "address unknown"
in case your DVB-CI capture tool can't figure out the COR address.
These two cases are checked by the patch. Thanks for feedback and/or merging
it.
