Subject: [dts][PATCH V2 1/2] test_plans/vhost_virtio_pmd_interrupt_cbdma_test_plan: modify the dmas parameter
Date: Fri, 11 Nov 2022 14:08:25 +0800 [thread overview]
Message-ID: <20221111060825.2421660-1-weix.ling@intel.com> (raw)
From DPDK-22.11, the dmas parameter have changed from
`lcore-dma=[lcore1@0000:00:04.0]` to `dmas=[txq0@0000:00:04.0]` by DPDK
local patch,so modify the dmas parameter.
