Subject: [PATCH net-next] net/mlx4_core: Test interrupts fail if not all comp vectors called request_irq
From: Carol L Soto <clsoto@...ux.vnet.ibm.com>
Test interrupts fails if not all completion vectors called
request_irq. This case can happen if only mlx4_en loads and
we have more completion vectors than rx rings.
