Bug ID: 1464
Summary: VLAN filtering bug
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Hi all,
I've written a test suite for VLAN features on DPDK drivers including
filtering, stripping, and insertion, but I've run into some issues
with Intel and Broadcom NICs. Both are forwarding packets when there are vlan
filter rules in place which should block packet forwarding.
To recreate the environment I'm running the tests on:
drivers: bnxt_en, i40e
Broadcom NIC info:
~$ ethtool -i ens2f0np0
driver: bnxt_en
version: 5.15.0-112-generic
firmware-version: 229.0.141.0/pkg 229.1.123.0
expansion-rom-version:
bus-info: 0000:61:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no
./dpdk-testpmd <EAL params> -- -i --portmask=0x3
testpmd> set fwd mac
testpmd> set promisc 0 off
testpmd> vlan set filter on 0
testpmd> rx_vlan add 1 0
testpmd> start
then, I build the following packet and send it to port 0 on testpmd:
packet = Ether()/Dot1Q(vlan=2)/Raw(load='xxxxx')
The Mellanox CX-5s show the expected behavior, where a packet with a VLAN tag
not in the filter list is dropped. However, with the Intel XL710
and Broadcom 57414 NICs, the packet is forwarded regardless of whether its VLAN
tag is in the filter list or not.

Any insight is appreciated.
