====================
10GbE Intel Wired LAN Driver Updates 2016-04-07

This series contains updates to ixgbe and ixgbevf.

This entire series (except for one patch from Alex) comes from Mark and
is mainly to add support for our new MAC (x550em_a).

So let's get Alex's patch out of the way first before we cover Mark's
many changes.  Alex does his enable bulk free in transmit cleanup for
ixgbe and ixgbevf, like his has done for all of our other drivers.

First Mark cleans up registers that were not being used, so do some
house cleaning.  Then to avoid casting lan_id and func fields, just
make them u8 since they only hold small values anyways.  Found and
fixed an issue where on read operations it could be possible to
modify locations beyond the length passed in, so change the check
to round up in the same way.  Cleaned up the interface for issuing
firmware commands to use a void * instead of a u32 * which eliminates
a number of casts.  Added support for the new MAC and provided method
pointers and use them to access IOSF-attached devices, since the
new MAC will also need a new access method.  Added support for SFPs
with an external retimer and for an SGMII backplane interface.
