firewire: net: set carrier state at ifup
At ifup, carrier status would be shown on even if it actually was off.
Also add an include for ethtool_ops rather than to rely on the one from
netdevice.h.
Note, we can alas not use fwnet_device_mutex to serialize access to
dev->peer_count (as I originally wanted). This would cause a lock
inversion:
- fwnet_probe | takes fwnet_device_mutex
+ register_netdev | takes rtnl_mutex
- devinet_ioctl | takes rtnl_mutex
+ fwnet_open | ...must not take fwnet_device_mutex
Hence use the dev->lock spinlock for serialization.
