From 0672a0918374036b7dffd9e60eeb63213e994f1b Mon Sep 17 00:00:00 2001 From: Neerav Parikh Date: Tue, 1 Apr 2014 07:11:47 +0000 Subject: [PATCH] i40e: Redistribute queue vectors after DCB reconfiguration The queue vectors are originally distributed among the total number of queues that are configured for a given VSI. The number of queues that are configured for a VSI depends on the number of TCs that are enabled for the VSI at VSI setup/creation time. But, the total number of queues that are configured for a VSI may change based on change in the total number of TCs enabled as a result of change in DCB configuration based on DCBX. Hence, it is required for the queue vectors to be redistributed when the total queues that are configured for a given VSI changes. Without redistributing the vectors the queues that are configured for the newly enabled TCs may not be able to do any Tx/Rx.
