Fix traceroute applet on the FreeBSD
This patch addressing 2 issues: 1. Replacing source/dest with uh_sport/uh_dport. It seems that uh_* members are defined on both Linux and BSD, so no #ifdef here 2. Use SOL_IPV6 instead of SOL_RAW on the FreeBSD to fix IPV6_CHECKSUM setsockopt Signed-off-by: Alex Samorukov <samm@os2.kiev.ua> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
