Do this on the command line (egit would work too but this is easier):
1. enable remote tracking so your local subfilter branch is always matched to the remote origin/subfilter - add this to the bottom of .git/config:
[branch "subfilter"]
remote = origin
merge = refs/heads/subfilter
2. git checkout -b subfilter origin/subfilter
3. git pull
Now you are on the subfilter branch. To switch back to master do this:
git checkout master or in egit Teams -> Switch To -> master
**NOTE - the subfilter branch probably won't even compile for a while as we slowly make the needed changes to impalementers of IFilter
