[NET]: Inline net_device_stats
Network drivers which keep stats allocate their own stats structure then write a get_stats() function to return them. It would be nice if this were done by default. 1) Add a new "stats" field to "struct net_device". 2) Add a new feature field to say "this driver uses the internal one" 3) Have a default "get_stats" which returns NULL if that feature not set. 4) Change callers to check result of get_stats call for NULL, not if ->get_stats is set. This should not break backwards compatibility with older drivers, yet allow modern drivers to shed some boilerplate code. Lightly tested: works for a modified lguest network driver.
