59 * KNI uses NET_NAME_UNKNOWN macro to select correct version of alloc_netdev()
60 * For old kernels just backported the commit that enables the macro
61 * (685343fc3ba6) but still uses old API, it is required to undefine macro to
62 * select correct version of API, this is safe since KNI doesn't use the value.
63 * This fix is specific to RedHat/CentOS kernels.
