Hi, I have a single port Mellanox ConnectX 4 100GbE NIC and I want to test its Rx/Tx capabilites using DPDK. My system runs a Linux kernel 4.4 compiled from sources.
I found the PMD driver for this NIC as provided by Mellanox here <http://www.mellanox.com/page/products_dyn?product_family=209&mtag=pmd_for_dpdk> . Following this <http://www.mellanox.com/related-docs/prod_software/MLNX_DPDK_Quick_Start_Guide_v2.2_2.7.pdf> guideline, I put my NIC in Ethernet mode, configured the 3 options regarding mlx5 in the config/common_linuxapp file and applied 'make install T=x86_64-native-linuxapp-gcc'. Then, I stumbled upon a compilation problem in the mlx4 module. The compiler's output is as follows: == Build drivers/net/mlx4 CC mlx4.o In file included from /usr/include/linux/if.h:31:0, from /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:57: /usr/include/linux/hdlc/ioctl.h:73:14: error: ?IFNAMSIZ? undeclared here (not in a function) char master[IFNAMSIZ]; /* Name of master FRAD device */ ^ /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:612:53: error: ?struct ifreq? declared inside parameter list [-Werror] priv_ifreq(const struct priv *priv, int req, struct ifreq *ifr) ^ /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:612:53: error: its scope is only this definition or declaration, which is probably not what you want [-Werror] /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c: In function ?priv_ifreq?: /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:619:32: error: dereferencing pointer to incomplete type ?struct ifreq? if (priv_get_ifname(priv, &ifr->ifr_name) == 0) ^ /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c: In function ?rxq_setup?: /opt/MLNX_DPDK_2.2_2.7/drivers/net/mlx4/mlx4.c:3735:29: error: unused parameter ?inactive?
