this way of compare cause wrong interface name been matched

[yintao1995]

for example，if the first port in iteration is "Ethernet42"， but searching target is “Ethernet4”, then match will be met.

which cause： i use command "teamdctl PortChannel01 state item get ports.Ethernet4.ifinfo.ifname" but i got is: "Ethernet42"
