The compile errors are as follows. The fixes came from standard
Linux drivers of ixgbe-3.21.2 and igb-5.1.2.

* Oracle Linux6.4
lib/librte_eal/linuxapp/kni/ethtool/ixgbe/kcompat.h:3111:
error: redefinition of 'ether_addr_equal'
include/linux/etherdevice.h:180: note: previous definition
of 'ether_addr_equal' was here
* RHEL6.5
lib/librte_eal/linuxapp/kni/ethtool/igb/kcompat.h:3597:
error: redefinition of 'mmd_eee_cap_to_ethtool_sup_t'
include/linux/mdio.h:387: note: previous definition of
'mmd_eee_cap_to_ethtool_sup_t' was here
lib/librte_eal/linuxapp/kni/ethtool/igb/kcompat.h:3625:
error: redefinition of 'mmd_eee_adv_to_ethtool_adv_t'
include/linux/mdio.h:415: note: previous definition of
'mmd_eee_adv_to_ethtool_adv_t' was here
lib/librte_eal/linuxapp/kni/ethtool/igb/kcompat.h:3653:
error: redefinition of 'ethtool_adv_to_mmd_eee_adv_t'
include/linux/mdio.h:443: note: previous definition of
'ethtool_adv_to_mmd_eee_adv_t' was here
