Subject: [PATCH] net: Remove variables hooks when interface is unregisted
|
|
|
|
The grub_net_network_level_interface_unregister(), previously
|
|
implemented in a header, did not remove the variables hooks that
|
|
were registered in grub_net_network_level_interface_register().
|
|
Fix this by implementing the same logic used to register the
|
|
variables and move the function into the grub-core/net/net.c.
