Hello Everyone,
I am facing an issue while bringing up vpp with *less than 2 rx and 2 tx
queue*. I am using vpp19.08. I have configured pci's under the dpdk section
like below -
1)
dpdk {
# dpdk-config
dev default {
num-rx-desc 1024
num-rx-queues 1
num-tx-desc 1024
num-tx-queues 1
# vlan-strip-offload off
}
dev 0000:1b:00.0 {
}
dev 0000:13:00.0 {
}
}
When I bring pci state to up , it is showing error in "show
hardware-interfaces"
DBGvpp# set interface state GigabitEthernet13/0/0 up
DBGvpp# show hardware-interfaces
Name Idx Link Hardware
GigabitEthernet13/0/0 1 down GigabitEthernet13/0/0

2) When bring up system without "*dev default* " section , still facing the
same issue , this time default [Rx-queue is 1 and tx-queue is 2 (main
thread + 1 worker)]
