add macvlan error -- kata-runtime 1.3.1

[coos]

1、add some json in /etc/docker/daemon.json：

"runtimes": {
        "kata-runtime": {
            "path": "/opt/kata/bin/kata-runtime"
        }
    }

2、run containers：

root# /opt/kata/bin/kata-runtime --version
kata-runtime  : 1.3.1
   commit   : 258eae021387b7fffee48a120e6b5afdd7c78a00

/cc @egernst, @mcastelino, @amshinde.

[mcastelino]

@coos we are in the process of adding support for a different networking mode in Kata which uses port mirroring. Once that is merged in you should be able to use both macvlan and ipvlan.

The PR that is in progress is #827

[amshinde]

@mcastelino We had added in an implementation based on macvtap earlier.
@jcvenegas I just verified that this works on master but not on release 1.3.1. Did this not go in 1.3.1?

[mcastelino]

@amshinde the macvtap solution requires a modified CNI plugin right? The port mirroring option lets the use macvlan itself vs mactap?

[jcvenegas]

@amshinde the only network related PR that was backported to 1.3.1 was d267da7

[egernst]

This should probably just be in 1.4, once it comes, since it is a feature more than a bug fix.

[amshinde]

Yes I agree, this should go in 1.4.
@coos This will be available in our 1.4 release.

[coos]

Thanks. When can I use 1.4 release?
