a specific question...

[R. Engür Pişirici]

  Hello All,

Before starting to ask my question, I would like to apologize about 
asking a silly question.
Mostly, i always try to find answers by reading, searching, digging, 
etc.
However, i really couldnt find a proper answer for my question.

My question is about l2tp/pptp drivers in kernel.
pptp driver is in /drivers/net. But, l2tp driver is in /net
I want to know why they reside in different paths? What did i miss?

Best Regards,
