First, create a new branch

git checkout -b <some_branch_name>

Second, make changes and commit them within that new branch

<changes…> git add git commit -m ””

Now it is time to create a patch and there are two ways to do that: (1) with a cover letter; and (2) without a cover letter

With cover letter

git format-patch master —cover-letter

Without cover letter

git format-patch master

Then format the patch (generated files)

Right before sending the patch let’s check it using provided script

make check ./utilities/checkpatch.py <patch_file>

Now, it is time to submit patch

git send-email

Note

• email address to send patches for OvS: dev@openvswitch.org

• If you get an error: “git: ‘send-email’ is not a git command” then you may need to install a required package:

sudo apt install git-email

• If you get an error: “Unable to initialize SMTP properly” then you may need to configure ‘gitconfig’.

Open the config

git config -e

and add the following lines:

[sendemail] from = sergey.madaminov@gmail.com smtpserver = smtp.gmail.com smtpserverport = 587 smtpencryption = tls smtpuser = sergey.madaminov@gmail.com
