port bonding to centos 8.5 on dl380 g9

I bonded two ports on 951Ui-2HnD 6.49.1 and centos 8.5 on dl380 g9 which is directly connected to the router, but there are lots of dropped packets. both links are ok in single mode.

# /etc/sysconfig/network-scripts/ifcfg-bond0
BONDING_OPTS="mode=0 downdelay=0 miimon=100 updelay=0"
TYPE=Bond
BONDING_MASTER=yes
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV6INIT=no
NAME=bond0
UUID=c75b21a1-c8d8-4517-8beb-12dc2e3c0a49
DEVICE=bond0
ONBOOT=yes
PROXY_METHOD=none
IPV4_FAILURE_FATAL=no
IPV6_DISABLED=yes

# /etc/sysconfig/network-scripts/ifcfg-eno1
TYPE=Ethernet
NAME=eno1
DEVICE=eno1
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
UUID=abf4c85b-57cc-4484-4fa9-b4a71689c359

# /etc/sysconfig/network-scripts/ifcfg-eno2
TYPE=Ethernet
NAME=eno2
DEVICE=eno2
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
UUID=b186f945-cc80-911d-668c-b51be8596980

I tired rr, 802.3ad with different hash policies, tlb, alb but none of them work. in tlb or alb when one of the ports are disabled it works normally.
Odd thing is if bonding interface is in bridge it even disrupts other connection in the bridge.
Now I switched to ubuntu and setup bonding during installation, and it doesn't work either. I think this is a Mikrotik bug.
I would really appreciate if someone has successfully done this tell what I'm missing.

After wasting so much time I found out that 951Ui-2HnD port bonding is buggy. I was just testing on this device, but on RB2011UiAS-2HnD-IN or CCR1009-7G-1C-1S+ it works with no problem. for anyone facing similar issues remember some features may not work well on lower end devices. thank you Mikrotik
