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 :
