igc: add support to get MAC Merge data via ethtool
Implement "ethtool --show-mm" callback for IGC.
Tested with command:
$ ethtool --show-mm enp1s0.
MAC Merge layer state for enp1s0:
pMAC enabled: on
TX enabled: on
TX active: on
TX minimum fragment size: 64
RX minimum fragment size: 60
Verify enabled: on
Verify time: 128
Max verify time: 128
Verification status: SUCCEEDED
Verified that the fields value are retrieved correctly.
