In this series following problems addressed: 1) Size of IFLA_GRE_LINK attribute is 32 bits long in , not 8 bit.
2) Use get_addr() instead of get_prefix() to parse local/remote tunnel endpoints as IPADDR, not PREFIX as per ip-link(8). 3) No need to check if local/remote endpoints are zero (e.g. INADDR_ANY): it is fully legal value, accepted by the kernel. See individual patch description message for details.
