Bonding support and quick link failover

[Mansoor]

I am working on enabling Linux Bonding feature where the Copper (IGB) and Fibre (ICE) ports are slaves of a bond interface.

I would like to understand whether both these drivers support bonding and to what extent.

Specifically, do these drivers support APIs like netif_carrier_ok().

https://www.kernel.org/doc/Documentation/networking/bonding.txt

use_carrier

  Specifies whether or not miimon should use MII or ETHTOOL

  ioctls vs. netif_carrier_ok() to determine the link

  status. The MII or ETHTOOL ioctls are less efficient and

  utilize a deprecated calling sequence within the kernel.  The

  netif_carrier_ok() relies on the device driver to maintain its

  state with netif_carrier_on/off; at this writing, most, but

  not all, device drivers support this facility.

We have stringent requirements to do a faster switchover from active to backup slave link during link failover.

That needs the drivers to respond faster to link status change and a subsequent faster response to switch role to active and start forwarding packets.

More details can be found here:
https://docs.kernel.org/networking/operstates.html

Appreciate any leads in this regard.

Hi Mansoor,

We might have a forum for those specific issues and we are moving it to Embedded Connectivity so it can get answered accordingly.

Hello @Mansoor,

Thank you for contacting Intel Embedded Community.

I'm not sure why this has been transferred almost 50 days after but I checked that you could use our IPS support regarding this matter, so I'm not adding much through here.

Best regards,
