From 4e55f5785825f18b1eb6c5cc5a9717e276925805 Mon Sep 17 00:00:00 2001 From: "Jorge Boncompte [DTI2]" Date: Mon, 21 Nov 2011 10:25:57 +0000 Subject: atm: Introduce vcc_process_recv_queue This function moves the implementation found in the clip and br2684 modules to common code, correctly unlinks the skb from the queue before pushing it and makes pppoatm use it.
