Error of "implicit-function-declaration" can be seen when building
KNI kernel module on Linux kernel 3.6.10 platform.
The root cause is as follows.
On Linux kernel 3.6.10, ETHTOOL_GEEE is defined in Linux header file
of "linux/ethtool.h", while is not defined in most of other
linux kernel versions.
mmd_eee_cap_to_ethtool_sup_t(), mmd_eee_adv_to_ethtool_adv_t() and
ethtool_adv_to_mmd_eee_adv_t() in kcompat.h are disabled by
"#if !defined(ETHTOOL_GEEE) || (RHEL_RELEASE_CODE && RHEL_RELEASE_CODE
<= RHEL_RELEASE_VERSION(6,4))", while are called in igb_get_eee()
in igb_ethtool.c which is enabled by "#ifdef ETHTOOL_GEEE".
This patch is to fix the compile issue.
