====================
ibmvnic: Tunable parameter support

This series implements support for changing tunable parameters such as the
mtu, number of tx/rx queues, and number of buffers per queue via ethtool
and ifconfig.

v2: -Fix conflict with Tom's recently applied TSO/SG patches
v3: -Initialize rc in __ibmvnic_reset fixing build warning
    -Fix buggy behavior with pending mac changes. Use boolean flag
     to track if mac change is needed on open rather than relying on
     the desired->mac pointer.
    -Directly include tunable structs in the adapter struct rather
     than keeping pointers, eliminating the need to directly allocate
     them.
