From eb3ca2a36f0c613aea5c2f02762bc608d5ec785c Mon Sep 17 00:00:00 2001 From: Joshua Oreman Date: Mon, 15 Jun 2009 11:37:43 -0700 Subject: [netdevice] Add netdev argument to link-layer push and pull handlers In order to construct outgoing link-layer frames or parse incoming ones properly, some protocols (such as 802.11) need more state than is available in the existing variables passed to the link-layer protocol handlers. To remedy this, add struct net_device *netdev as the first argument to each of these functions, so that more information can be fetched from the link layer-private part of the network device. Updated all three call sites (netdevice.c, efi_snp.c, pxe_undi.c) and both implementations (ethernet.c, ipoib.c) of ll_protocol to use the new argument.
