It is not present in the latest FreeBSD source:

http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/netinet/ip_var.h?rev=1.101

but that source does have "#ifdef __NO_STRICT_ALIGNMENT" support. I am not 
sure what this means. The latest code may have support else where to handle 
the alignment. That is, the packing you show may be needed for the version of 
the stack we have.
