Release 4.12 include/linux/netfilter_ipv4/ip_tables.h
/*
* 25-Jul-1998 Major changes to allow for ip chain table
*
* 3-Jan-2000 Named tables to allow packet selection for different uses.
*/
/*
* Format of an IP firewall descriptor
*
* src, dst, src_mask, dst_mask are always stored in network byte order.
* flags are stored in host byte order (of course).
* Port numbers are stored in HOST byte order.
