From: Roopa Prabhu <ro...@cumulusnetworks.com>
This is similar to command options corresponding to other NTF_* flags
already exposed to the user space (examples self/master).
Also updates bridge man page (The man page patch also includes
a fix to the 'self' entry and documents 'master' for fdb entries)
