I started Ethernet through PCIe according to the requirements on the official website(Bringing up an Ethernet Interface over PCIe).
After performing the following configuration,
# cd /sys/kernel/config/pci_ep/
# mkdir functions/pci_epf_tvnet/func1
# echo 16 > functions/pci_epf_tvnet/func1/msi_interrupts
# ln -s functions/pci_epf_tvnet/func1 controllers/141a0000.pcie_ep/
# echo 1 > controllers/141a0000.pcie_ep/start
the following problem occurred:
connection failed Activation of network connection failed
When I set the following network configuration, the network cannot be pinged
1. On the endpoint device: ifconfig eth1 up
2. On the root port system: ifconfig eth1 up
3. On the endpoint device: ifconfig eth1 192.168.2.1
4. On the root port system: ifconfig eth1 192.168.2.2
At the same time, the ARP table entry displays “incomplete”
