For bug fixing, it is required to reference the id of the commit which introduced the bug.
You can generate the required lines using the following git alias:
''' git config alias.fixline "log -1 --abbrev=12 --format='Fixes: %h (\"%s\")%nCc: %ae'"  '''
and then put the output of ''' git fixline <SHA> ''' into the commit message.

And also be CCed to the stable at dpdk.org mailing list. Thanks!

Regards,
Junfeng
