Hello Intel Team

We found one big problem(Bug) in intel i40e driver .

expansion-rom-version:
bus-info: 0000:02:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

Problem is this :

Problem is flood dmesg and networking stop work on this time of message .

do you have any idea how to fix or patch i40e driver to fix this problem.

on machine is configured this interface only :

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP
group default qlen 10000
    link/ether 0c:c4:7a:19:70:18 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group
default qlen 1000
    link/ether 0c:c4:7a:19:70:19 brd ff:ff:ff:ff:ff:ff
4: eth0.0101 at eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc
noqueue state UP group default qlen 1000
    link/ether 0c:c4:7a:19:70:18 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.2/27 scope global eth0.0101
       valid_lft forever preferred_lft forever

Normaly problem stop when make this :

ethtool -K eth0 rx-vlan-filter off
Actual changes:
rx-vlan-filter: on [requested off]
Could not change any device features

But in this card this options is hard set on ON and i not found
options to disable.
