[Intel-wired-lan] [PATCH net v1 0/3] ice: Fixes for double vlan promiscuous mode

[Grzegorz Siwik]

This series fixes known issues related to double vlan promiscuous mode.
When at least two interfaces are bonded and a bridge is enabled on the
bond, an error can occur when the bridge is removed and re-added. The
reason for the error is because promiscuous mode was not fully cleared from
the VLAN VSI in the hardware.
Ignore ERR_ALREADY_EXISTS error when setting promiscuous mode.
This fix is needed because the driver could set promiscuous mode
when it still has not cleared properly.
Avoid enabling or disabling vlan 0 when trying to set promiscuous
vlan mode if double vlan mode is enabled. This fix is needed
because the driver tries to add the vlan 0 filter twice (once for
inner and once for outer) when double VLAN mode is enabled.

[Intel-wired-lan] [PATCH net v1 1/3] ice: Fix double VLAN error when entering promisc mode

[Grzegorz Siwik]

Avoid enabling or disabling vlan 0 when trying to set promiscuous
vlan mode if double vlan mode is enabled. This fix is needed
because the driver tries to add the vlan 0 filter twice (once for
inner and once for outer) when double VLAN mode is enabled. The
filter program is rejected by the firmware when double vlan is
enabled, because the promiscuous filter only needs to be set once.

This issue was missed in the initial implementation of double vlan
mode.

creating bridge over bond and then double vlan

Hi,

Is it regression introduced by this patch or this fix is partial and
mentioned issue is unfixed regression from past. I asking because
promisc mode issues is very pain for us and in second case will be
(maybe) good to move this forward and mentioned issue will fix in next
patch.

Many thanks,
Petr

Hi,
We are currently investigating what is wrong with that - it is possible that i have something missed in upstreaming one of these patches. 
We let know when we find what is wrong.

Grzegorz

Hi Guys,

We found what is wrong - we have not backported one of the patch from RedHat - so i didn't know that this problem could exist.
Soon we will send fix for reported issues.

Best Regards,
Grzegorz

[Intel-wired-lan] [PATCH net v1 2/3] ice: Ignore ERR_ALREADY_EXISTS when setting promisc mode

[Grzegorz Siwik]

Ignore ERR_ALREADY_EXISTS error when setting promiscuous mode.
This fix is needed because the driver could set promiscuous mode
when it still has not cleared properly.
Promiscuous mode could be set only once, so setting it second
time will be rejected.

[Intel-wired-lan] [PATCH net v1 3/3] ice: Fix clearing of promisc mode with bridge over bond

[Grzegorz Siwik]

When at least two interfaces are bonded and a bridge is enabled on the
bond, an error can occur when the bridge is removed and re-added. The
reason for the error is because promiscuous mode was not fully cleared from
the VLAN VSI in the hardware. With this change, promiscuous mode is
properly removed when the bridge disconnects from bonding.

Re: [Intel-wired-lan] [PATCH net v1 0/3] ice: Fixes for double vlan promiscuous mode

[Petr Oros]

> This series fixes known issues related to double vlan promiscuous

> cleared from

> Ignore ERR_ALREADY_EXISTS error when setting promiscuous mode.
> This fix is needed because the driver could set promiscuous mode
> when it still has not cleared properly.
> Avoid enabling or disabling vlan 0 when trying to set promiscuous
> vlan mode if double vlan mode is enabled. This fix is needed
> because the driver tries to add the vlan 0 filter twice (once for
> inner and once for outer) when double VLAN mode is enabled.
