Install PHY and MDIO bus drivers and the driver of physical device for a SR-IOV virtual device

[coiby]

This PR fixes three cases where network dumping fails,

• PHY drive is missing
• MDIO bus driver is missing
• a NIC is a Single Root I/O Virtualization (SR-IOV) virtual device

not seeing the "Resolves" field in this commit, not sure if this is necessary.

The second commit currently has no reported issue.

Otherwise, this looks good to me.

Ack

LGTM

Thanks for reviewing the patches!
