From ff7e93219442f5ac5b2cfd33e4fe4b7d5942f957 Mon Sep 17 00:00:00 2001 From: Brett Creeley Date: Mon, 28 Jun 2021 10:53:45 -0700 Subject: ice: Fix failure to re-add LAN/RDMA Tx queues Currently if the VSI is rebuilt/removed and the RDMA PF driver is active the RDMA Tx queue scheduler node configuration will not be cleaned up. This will cause the rebuild/re-add of the VSI to fail due to the software structures not being correctly cleaned up for the VSI index. Fix this by always calling ice_rm_vsi_rdma_cfg() for all VSI. If there are no RDMA scheduler nodes created, then there is no harm in calling ice_rm_vsi_rdma_cfg(). This change applies to all VSI types, so if RDMA support is added for other VSI types they will also get this change.
