From 98a82febb6340466824c3a453738d4fbd05db81a Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 24 Aug 2005 11:35:51 -0700 Subject: [PATCH] [AX25/NETROM]: Cleanup direct calls into IP stack Get rid of the calls to ip_rcv and arp_rcv which were layering violations anyway. With those being replaced by netif_rx, less parts of AX.25 and relatives depend on INET support actually being enabled. This also will make PF_PACKET sockets work for IP and ARP packets received over AX.25 and for IP packets over NET/ROM. Signed-off-by: Ralf Baechle DL5RB Signed-off-by: David S.
