Subject: [PATCH v3 2/8] net/ixgbe: enable vector stubs for RISC-V
Date: Tue, 10 May 2022 17:48:43 +0200	[thread overview]
Message-ID: <20220510154849.530872-3-kda@semihalf.com> (raw)
In-Reply-To: <20220510154849.530872-1-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.
