Except that this totally happens if you set RHEL_RELEASE_CODE to somthing larger
than (6,4).  ethtool_adv_to_mmd_eee_adv_t and its companion functions protected
by that if statement in kcompat.h are never declared in user space, as they are
not included in the uapi/mdio.h header, on in the kernel-specific mdio.h header.
Before you add a clause to include support for 6.5 and later, you need to remove
that if conditional and declare those functions unilaterally for any relase
beyond where it was defined in the kernel.
