*
* 2006-03-10 - version 0.3
* 1. Added support for multiple TPKTs in one packet (suggested by
* Patrick McHardy)
* 2. Added support for non-linear skb (based on Patrick McHardy's patch)
* 3. Eliminated unnecessary return code
*
* 2006-03-15 - version 0.4
* 1. Added support for T.120 channels
* 2. Added parameter gkrouted_only (suggested by Patrick McHardy)
