during the second week i extended the vale_vlan kernel module.
VLAN configuration can now be created (modified and read) through system
calls on the device "/dev/vale_vlan".
First a VLAN configuration must be selected though an ioctl(), which
expects a "struct vlanreq_header".
Then commands are issued to the configuration through a write(), which
expects an array "struct vlan_conf_entry". An array of commands is
considered atomic, therefore if one of them fails, the status of the
configuration is rolled back.
Finally the current configuration can be read though a read(), passing an
array of "struct port".
The data structures used by the interface between user and kernel space are
defined in "net/vale_vlan_user.h".
