vlan is not working when we upgrade linux kernel from 2.6.32-431.el6.i686
Tried e1000 drivers:
when testing with one of above e1000 driver versions, we have tried to use
intermediate kernel versions between working and failure of vlan trunking,
the results of uname are below.
kernel-2.6.32-431.el6.i686 - passed
kernel-2.6.32-504.23.4.el6.i686 -not working
kernel-2.6.32-504.30.3.el6.i686 - not working
kernel-2.6.32-573.3.1.el6.i686 -not working
Linux centos-6.5 2.6.36 -passed
Linux centos-6.5 3.5.0 - not working
we have tried both embedded and standalone drivers and the result is same.
the vlan tagged packets are received in linux and linux is removing its tag
and gives to our application. so we see vlan ping failure with "wrong
as mentioned in search forum, we have tried to turn on/off rx-vlan-filter
and offload setting, but we could not change it, as it is denoted as
just to confirm the issue with pcnet32 driver with failure kernel,
eventhough rx-vlan-filter is off as below, still facing issue.
[***@localhost drivers]# ethtool -k eth5 | grep vlan
rx-vlan-offload: off [fixed]
tx-vlan-offload: off [fixed]
rx-vlan-filter: off [fixed]
vlan-challenged: off [fixed]
we don't have the option to use e1000e driver.
Please let me know if any specific information is required. can you please
suggest us the latest stable kernel of 3.x version and e1000 driver
combination where rx vlan tagging works ?
Appreciate your inputs on this.
PS: below bug is raised. but as per Todd suggestion in below mail thread,
sending this email to alias.
