Enabling MPTCP

Enable MPTCP for the current session by running the following command:
```
sudo sysctl -w net.mptcp.enabled=1
```
Persist the change across system reboots.
To ensure that MPTCP remains enabled after the system reboots, run the following command to add net.mptcp.enabled=1 to the /etc/sysctl.conf file:
```
echo "net.mptcp.enabled=1" | sudo tee -a /etc/sysctl.conf
```
Reload the sysctl configuration to apply all persistent settings.
```
sudo sysctl -p
```
Verify that MPTCP is enabled:
```
sysctl net.mptcp.enabled
```
The expected output is:
```
net.mptcp.enabled = 1
```
