The Fixes tag just points us to the commit which introduced the bug,
look thru the git history of the kernel for examples. The expected
format is:

        fixes = Fixes: %h (\"%s\")

You need to find the oldest commit where problem exists. This helps
stable tree maintainers to backport the necessary fixes (and netdev
maintainers to make sure that the right tree is targeted).
