bpf: fix _htons occurences in test_progs
Dave reported that on sparc test_progs generates buggy swapped
eth->h_proto protocol comparisons:
10: (15) if r3 == 0xdd86 goto pc+9
R0=imm2,min_value=2,max_value=2 R1=pkt(id=0,off=0,r=14) R2=pkt_end R3=inv
R4=pkt(id=0,off=14,r=14) R5=inv56 R10=fp
This is due to the unconditional ...
#define htons __builtin_bswap16
#define ntohs __builtin_bswap16
... in test_progs that causes this. Make use of asm/byteorder.h
and use __constant_htons() where possible and only perform the
bswap16 when on little endian in non-constant case.
