Subject: qed: Always publish VF link from leading hwfn

From: "Mintz, Yuval" <[email protected]>

[ Upstream commit e50728effe1126eae39445ba144078b1305b7047 ]

The link information exists only on the leading hwfn, but some of its derivatives [e.g., min/max rate] need to be configured for each hwfn.
When re-basing the VF link view, use the leading hwfn information as basis for all existing hwfns to allow said configurations to stick.
