[support] McoA Failed to add policy

[Romain KUNTZ]

Hi Luis,

Indeed there was a nasty bug in the MCoA patch. I fixed it and  
uploaded a new NEPL and MCoA patch (version 20071105) on the NEPL  
Howto page: http://www.nautilus6.org/doc/nepl-howto/

I took the occasion to update a bit the NEPL patch too, so you'll  
have to use both 20071105 patches.
Would you mind patching & recompiling UMIP with those 2 patches and  
tell me if you still meet the problem?

Cheers,
Romain
