Subject: [PATCH 1/1] drivers/net: param for lapbether for specific ethernet
device

No need for this header.

The lapbether driver binds to the first ethernet device that comes up.
This causes problems in hardware with multiple ethernet interfaces,
potentially resulting in the LAPB traffic on the wrong interface.
Have added a module parameter 'eth_dev' to specify the ethernet
interface over which lapbether should operate. The module behaves
as before if no device is specified.

Patch created on linux-next 18-Jun-2013.
Tested on 2.6.32-45-generic.

Your patch is line-wrapped.

switch (event) {
case NETDEV_UP:
/* New ethernet device -> new LAPB interface */
- if (lapbeth_get_x25_dev(dev) == NULL)
- lapbeth_new_device(dev);
+ if (lapbeth_get_x25_dev(dev) == NULL) {
+ if (NULL != eth_dev) {
+ if (0 == strcmp(dev->name, eth_dev))
+ lapbeth_new_device(dev);
+ } else {
+ lapbeth_new_device(dev);
+ }
+ }

It seems the patch is also white space damaged, i.e. tabs converted to spaces.

WBR, Sergei
