Re: [dpdk-dev] [PATCH v3 0/3] Mellanox ConnectX-3 PMD

[Gleb Natapov <gleb@cloudius-systems.com>]

Did git pull today. After enabling mlnx pmd compilation fails with:

dpdk/lib/librte_pmd_mlx4/mlx4.c: In function ‘mlx4_pci_devinit’:
dpdk/lib/librte_pmd_mlx4/mlx4.c:4636:14: error: too few arguments to function ‘rte_eth_dev_allocate’
    eth_dev = rte_eth_dev_allocate(name);
