Subject: [PATCH v4 2/8] net/ixgbe: enable vector stubs for RISC-V
Date: Tue, 31 May 2022 16:13:01 +0200 [thread overview]
Message-ID: <20220531141307.253385-3-kda@semihalf.com> (raw)
In-Reply-To: <20220531141307.253385-1-kda@semihalf.com>
Re-use vector processing stubs in ixgbe PMD defined for PPC for RISC-V.
This enables ixgbe PMD usage in scalar mode on this architecture.
The ixgbe PMD driver was validated with Intel X520-DA2 NIC and the
test-pmd application. Packet transfer checked using all UIO drivers
available for non-IOMMU platforms: uio_pci_generic, vfio-pci noiommu and
igb_uio.
