[ovs-discuss] Reg error when submitting patch.

[Krishna Kolakaluri]

Hi All,
         I submitted two patches to ovs-dev and I get an error saying
git-am "fatal: patch fragment without header at line 6". Can somebody
help me what is wrong here.

I used git format-patch as described in Documentation/internatls/contributing/.

The patch which caused the error is below:
