qeth network driver changes:
 - Improve performance by omitting svs.
 - Use function callback mechanism to set layer 2 parameters when getting
   a reply for a Layer 2 command.
 - dev->hard_header must not be NULL when fake_ll is no set since
   IPv6 and Layer2 needs the default function set by network stack.
 - ping6 works now when running in layer 2 mode.
 - Save original dev->hard_header to restore it when the user doesn't
   want to use fake_ll anymore.
 - Fake ethernet header in outgoing packets. This currently works
   only if qeth is compiled without ipv6 support.
 - Add more debug information in case of failures in qeth_set_offline.
 - Using fake_ll with HiperSockets devices results in misaligned
   ip packets and thus no traffic over HiperSockets.
 - Start qeth_remove_device only after the qeth recovery completed.
