From 4c8b99f6b1ff086c1745fcb0511800fba5c4fb34 Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Thu, 29 Jun 2017 11:10:44 +0300 Subject: [PATCH] nvme-rdma: update tagset nr_hw_queues after reconnecting/resetting We might have more/less queues once we reconnect/reset. For example due to cpu going online/offline or controller constraints.
