+Subject: [PATCH] Tweak cargo.toml to work with vendor directory
+
+Mock works offline, cargo would try to download the files from github.
+So cargo vendor has to be run first, and then change the Cargo.toml to
+make mock happy.
+
+(cherry picked from commit 0d5347bd771e960294cd0c2f083d96448613ab9c)
