hello,

I’m still trying vpp operation on the cn9130-cf-pro board.  
On the CN9130-CF-PRO board, eth0 was successfully created with VPP’s MV-PPIO-0/0 interface.

```auto
DBGvpp# show int
              Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count
local0 0 down 0/0/0/0
DBGvpp# create interface marvell pp2 name eth0
DBGvpp# show int
              Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count
local0 0 down 0/0/0/0
mv-ppio-0/0 1 down 9000/0/0/0

```

However, if you try to create an interface from vpp for eth2, an error occurs and is not created.  
It’s the same if you try eth1.

```auto
DBGvpp# create interface marvell pp2 name eth2
[1582.121115] [ERROR] [pp2_bpool_init] bm_pool already exists.
create interface marvell pp2: bpool 'pool-0:8' init failed
DBGvpp# show int
              Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count
local0 0 down 0/0/0/0
mv-ppio-0/0 1 down 9000/0/0/0
DBGvpp#

```

VPP receives the UIO device information in ‘/sys/class/uio’ from the MUSDK.  
If you know anything about this issue, please respond.

thank you
