You should test your program before submiting:

/tmp/temp/bpf: make
gcc -c -g -DDEBUG -I/usr/include -I/usr/local/include bpf.c -o bpf.o
bpf.c:24: parse error before `.'
bpf.c: In function `main':
bpf.c:139: `if_data' undeclared (first use this function)
bpf.c:139: (Each undeclared identifier is reported only once
bpf.c:139: for each function it appears in.)
bpf.c: At top level:
bpf.c:205: parse error before `.'
*** Error code 1

bpf.c
25:char           *if_type();
