No, it's not caused by the lapi/ip_tables.h which finally includes
<linux/if.h>.
See experiment commit:
https://github.com/wangli5665/ltp/commit/f1a37712c63472b19d3355446fb66e651b4a186e
The conflict happened early in tst_test.h and I guess some header files
between line#14 to line#44 probably involves <linux/if.h>, but I'm not sure
which one is the culprit.
If we simply put the <netinet/in.h> at the top of tst_test.h, the
conflict disappears
as well.
