This patch adds an option to retrieve the per originator multicast flags table.
Signed-off-by: Linus Lüssing linus.luessing@web.de ---
Changes in v3: * updated mcast_flags example in README file
Changes in v2: * header_lines for 'mcast_flags' increased from 2 to 6 * Example updated to more verbose, 6 lines debugfs header output * (kept order for the noted manpage section as it wasn't alphabetically orderd in the first place - instead keeping the previous "logical" order - 'mcast' after 'nc')
