Subject: intel: Remove extern from function prototypes

There are a mix of function prototypes with and without extern
in the kernel sources.  Standardize on not using extern for
function prototypes.

Function prototypes don't need to be written with extern.
extern is assumed by the compiler.  Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

Subject: net:drivers/net: Miscellaneous conversions to ETH_ALEN

Convert the memset/memcpy uses of 6 to ETH_ALEN
where appropriate.

Also convert some struct definitions and u8 array
declarations of [6] to ETH_ALEN.

Subject: igbvf: integer wrapping bug setting the mtu

If new_mtu is very large then "new_mtu + ETH_HLEN + ETH_FCS_LEN" can
wrap and the check on the next line can underflow. This is one of those
bugs which can be triggered by the user if you have namespaces
configured.

Also since this is something the user can trigger then we don't want to
have dev_err() message.

This is a static checker fix and I'm not sure what the impact is.
