include/netinet/if_ether.h: add ethhdr definition.

adapts to third-party code compilation. in the process of porting EtherCAT, we encounter some situations where the structure is not defined, or the returned data types do not match the expectations. Refer to the EtherCAT implementation of other systems and add relevant definitions. Signed-off-by: zhanghongyu <[email protected]>
