>Description:
My userppp stops working since upgrading CVS trunk of 2006-03-24.
Error message:
ppp[715]: Error: ip_Input: deflink: wrote 40, got Address family not supported 
by protocol family

Reverting to kernel of 2006-02-20 fixes it.

>How-To-Repeat:

>Fix:
I have only a workaround. The following patch breaks userppp on older kernel, 
probably.
