You can use any git tool to search in history.
I like using gitk.
I searched when the lines you changed were introduced.
This kind of search is called pickaxe in git docs.

When you found the SHA1, you can use this git alias to generate the Fixes line:
	fixline = log -1 --abbrev=12 --format='Fixes: %h (\"%s\")%nCc: %ae'

Or even more complex to add the Cc: stable@dpdk.org line automatically:
	fixline = "!f () { git log -1 --abbrev=12 --format='Fixes: %h (\"%s\")%nCc: %ae' $1 ; ( git tag -l --contains $1 | head -n1 | sed 's,^v,,' | sed 's,-rc.*,,' ; for i in 1 2 ; do make showversion | cut -d'.' -f-2 ; done ) | uniq -u | head -n1 | sed 's,.*,Cc: stable@dpdk.org,' ;}; f"
