>Description:
According to the man page, we have this option.
in|out
Matches incoming or outgoing packets, respectively.  in and out are mutually exclusive (in	fact, out is implemented as not	in).

But below test case can demonstrate this feature is not working on FreeBSD10
>How-To-Repeat:
1. Create two lines of rule to filter in traffic and all traffic.
ipfw add count all from any to any MAC any any in via em0
ipfw add count all from any to any MAC any any via em0
2. Show the counters
00100    0      0 count ip from any to any MAC any any in via em0
00200   26   2232 count ip from any to any MAC any any via em0
65535 3453 293448 allow ip from any to any
