Subject: [PATCH] get inline functions work with both gnu11 and gnu89

After gcc upgraded to gcc5, and if the codes are compiled without optimization(-O0), and the below error will happen:

./include/lldp_8021qaz.h:237:12: error: inline function 'ieee8021qaz_clif_cmd' declared but never defined [-Werror]
 inline int ieee8021qaz_clif_cmd(void *data, struct sockaddr_un *from,
            ^
./include/lldp_8021qaz.h:222:13: error: inline function 'set_prio_map' declared but never defined [-Werror]
 inline void set_prio_map(u32 *prio_map, u8 prio, int tc);
             ^
./include/lldp_8021qaz.h:221:12: error: inline function 'get_prio_map' declared but never defined [-Werror]
 inline int get_prio_map(u32 prio_map, int tc);

gcc5 defaults to -std=gnu11 instead of -std=gnu89, and it requires that exactly one C source file has the callable copy of the inline function.
