Subject: qed: Correct MSI-x for storage

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

[ Upstream commit 2f78227874754b1e10cd348fd6e7693b0dabb3f6 ]

When qedr is enabled, qed would try dividing the msi-x vectors between L2 and RoCE, starting with L2 and providing it with sufficient vectors for its queues.

Problem is qed would also do that for storage partitions, and as those don't need queues it would lead qed to award those partitions with 0 msi-x vectors, causing them to believe theye're using INTa and preventing them from operating.
