From d7e1b1a4a63c7ad6d28863fa07d765844c3dc8e4 Mon Sep 17 00:00:00 2001 From: "Mintz, Yuval" Date: Wed, 5 Apr 2017 21:20:11 +0300 Subject: [PATCH] qed: Correct MSI-x for storage 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.
