      Description of problem:

      Provisioning interface on master node not getting ipv4 dhcp ip address from bootstrap dhcp server on OCP 4.10.16 IPI BareMetal install.

      Customer is performing an OCP 4.10.16 IPI BareMetal install and bootstrap node provisions just fine, but when master nodes are booted for provisioning, they are not getting an ipv4 address via dhcp. As such, the install is not moving forward at this point.

      Version-Release number of selected component (if applicable):

      OCP 4.10.16

      How reproducible:

      Perform OCP 4.10.16 IPI BareMetal install.

      Actual results:

      provisioning interface comes up (as evidenced by ipv6 address) but is not getting an ipv4 address via dhcp. OCP install / provisioning fails at this point.

      Expected results:

      provisioning interface successfully received an ipv4 ip address and successfully provisioned master nodes (and subsequently worker nodes as well.)

      Additional info:

      As a troubleshooting measure, manually adding an ipv4 ip address did allow the coreos image on the bootstrap node to be reached via curl.

      Further, the kernel boot line for the first master node was updated for a static ip addresss assignment for further confirmation that the master node would successfully image this way which further confirming that the issue is the provisioning interface not receiving an ipv4 ip address from the dhcp server.
