From 759ace7832802eaefbca821b2b43a44ab896b449 Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Thu, 1 Nov 2018 13:08:07 -0700 Subject: [PATCH] i40iw: remove support for ib_get_vector_affinity Devices that does not use managed affinity can not export a vector affinity as the consumer relies on having a static mapping it can map to upper layer affinity (e.g. sw queues). If the driver allows the user to set the device irq affinity, then the affinitization of a long term existing entites is not relevant. For example, nvme-rdma controllers queue-irq affinitization is determined at init time so if the irq affinity changes over time, we are no longer aligned.
