Description of problem:
The ip(7) man page indicates that IP_MULTICAST_IF takes an argument which is an ip_mreqn or ip_mreq structure. In reality, IP_MULTICAST_IF takes an argument which is an ip_mreqn or in_addr structure.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. man 7 tcp
2. Search for IP_MULTICAST_IF
3. Read which argument(s) it takes
man page claims that IP_MULTICAST_IF takes ip_mreqn or ip_mreq structure.
man page claims that IP_MULTICAST_IF takes ip_mreqn or in_addr structure.
LSB gets it wrong as well.
In all non-Linux implementations, IP_MULTICAST_IF takes an in_addr structure.
