Description Zvonko Kosic 2020-11-12 20:22:49 UTC 
Description of problem:

On a 4.6 converged master/worker cluster NFD workers are not deployed. 
We are tolerating all taints and repelling the nfd worker from the master. 
Now in the converged master/worker case we need also make sure that NFD worker is also scheduled on a node with master/worker label.
Comment 1 Walid A. 2020-11-17 21:26:11 UTC 
Verified on converged an upi on baremetal OCP 4.6.3 cluster, deployed NFD from github master branch after PRs have merged:

git clone https://github.com/openshift/cluster-nfd-operator.git
cd cluster-nfd-operator
make deploy
