This patch is causing the following build failure on CentOS 7 with gcc 4.8.5: """ drivers/librte_net_ice.a(net_ice_ice_rxtx.c.o): In function `ice_set_rx_function': drivers/net/ice/ice_rxtx.c:3034: undefined reference to `ice_recv_scattered_pkts_vec_avx512' drivers/net/ice/ice_rxtx.c:3050: undefined reference to `ice_recv_pkts_vec_avx512' drivers/librte_net_ice.a(net_ice_ice_rxtx.c.o): In function `ice_set_tx_function': drivers/net/ice/ice_rxtx.c:3243: undefined reference to `ice_xmit_pkts_vec_avx512' """ It reproduces when building with "meson --werror --buildtype=debug build && ninja -C build".
