[NET-2.6.24][VETH][patch 1/1] fix bad netif_carrier_off place

From: Daniel Lezcano <[EMAIL PROTECTED]> If the netif_carrier_off is called before register_netdev that will use and generate an event for a non initialized network device and that leads to a Oops. I moved the netif_carrier_off from the setup function after each register_netdev call. Signed-off

[net-2.6.24][patch 1/2] Dynamically allocate the loopback device - mindless changes

From: Daniel Lezcano <[EMAIL PROTECTED]> This patch replaces all occurences to the static variable loopback_dev to a pointer loopback_dev. That provides the mindless, trivial, uninteressting change part for the dynamic allocation for the loopback. Signed-off-by: Eric W. Biederman <[EMAIL PROTECTE

[net-2.6.24][patch 0/2] Dynamically allocate the loopback

This patch allows to dynamically allocate the loopback like an usual network device. This global static variable loopback_dev has been replaced by a netdev pointer and the init function does the usual allocation, initialization and registering of the loopback. This patchset is splitted in two par

From: Daniel Lezcano <[EMAIL PROTECTED]> The macro definition is bad. When calling next_net_device with parameter name "dev", the resulting code is: struct net_device *dev = dev and that leads to an unexpected behavior. Especially when llc_core is compiled in, the kernel panics at boot
