Description
i'm using this card "Broadcom BCM57454 NIC", when i bind it with dpdp is shows it is binded with vfio-pci driver, but even though mentioning it in the startup.conf file it does not shows the interface in vpp:
startup.conf:
memory {
main-heap-size 4G
main-heap-page-size 2M
}
buffers {
buffers-per-numa 128000
default data-size 2048
}
dpdk {
Configuration for the first port
dev 0000:b5:00.0 {
# Corrected to 16 queues to stay within hardware limits (16+16=32 < 63)
num-rx-queues 16
num-tx-queues 16
}
Configuration for the second port
dev 0000:b5:00.1 {
# Corrected to 16 queues to stay within hardware limits
num-rx-queues 16
num-tx-queues 16
}
dev 0000:22:00.0 {
num-rx-queues 1
num-tx-queues 1
}
dev 0000:22:00.1 {
num-rx-queues 1
num-tx-queues 1
}
dev 0000:22:00.2 {
num-rx-queues 1
num-tx-queues 1
}
dev 0000:22:00.3 {
num-rx-queues 1
num-tx-queues 1
}
the error it throws is :
