samples/bpf sock_example: Avoid getting ethhdr from two includes
To avoid the following build failure on Alpine Linux 3.4, that has
clang-3.8 with the bpf target:
HOSTCC samples/bpf/sock_example.o
In file included from /usr/include/net/ethernet.h:10:0,
from /git/linux/samples/bpf/sock_example.h:7,
from /git/linux/samples/bpf/sock_example.c:30:
/usr/include/netinet/if_ether.h:96:8: error: redefinition of 'struct
ethhdr'
struct ethhdr {
^
In file included from /git/linux/samples/bpf/sock_example.c:26:0:
./usr/include/linux/if_ether.h:144:8: note: originally defined here
struct ethhdr {
^
scripts/Makefile.host:124: recipe for target
'samples/bpf/sock_example.o' failed
make[2]: *** [samples/bpf/sock_example.o] Error 1
/git/linux/Makefile:1658: recipe for target 'samples/bpf/' failed
So include net/if_ether.h for the needs of sock_example.h, using the
same include that sock_example.c uses.
