qed: Limit msix vectors in kdump kernel to the minimum required count.
[ Upstream commit bb7858ba1102f82470a917e041fd23e6385c31be ]
Memory size is limited in the kdump kernel environment. Allocation of more
msix-vectors (or queues) consumes few tens of MBs of memory, which might
lead to the kdump kernel failure.
This patch adds changes to limit the number of MSI-X vectors in kdump
kernel to minimum required value (i.e., 2 per engine).
Fixes: fe56b9e6a ("qed: Add module with basic common support")
