Don't leave the commit message empty. Explain the change and include an example output showing the "locked" flag.
bridge/fdb.c | 11 +++++++++--
Still missing a description of the "locked" flag from the man page. Something like:
" locked - this entry was added by the kernel in response to a host trying to communicate behind a bridge port with MAB enabled. User space can authenticate the host by clearing the flag. The flag cannot be set by user space. "
