What's the difference between the in-kernel ethernet drivers and intel drivers like i40e, ixgbe, e1000e, igb?

[KDutt]

We are in the process of build a new release for Seagate Linux OS. I'm now scratching my head whether to pick the in-kernel stock drivers or go with the latest intel drivers?

It's a CentOS based OS, so it's rpm based.

The target drivers that I'm looking at are: i40e, ixgbe, e1000e, igb

I have system with adapters that need either e1000e and/or igb/ixgbe, where as i40e would be needed for the HBA cards.

Please advise.

Hi /home/kk,

Thank you for the post. Just wondering what is the network adapter to be used as the driver we have are for the Intel network adapter.rgds,wb

Hello,

Thanks for the response. In our Seagate controllers we have variety of intel adapters, here's a few of them what I see from lspci output:

01:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) --> igb driver

05:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection --> e1000e driver

05:00.0 Ethernet controller: Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 (rev 01) --> ixgbe driver

00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I217-LM (rev 05) --> e1000e again

00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 06) -> e1000e

The above outputs are obviously from different Seagate cloud controllers.

Hence I need all of e100e, igb, and ixgbe drivers, plus for some of the hba cards I need the i40e driver as well.

The applications that use these interfaces are somewhere in MPI and HPC space.

For igb I'm going to use the stock kernel driver. I need some input regarding what extras I have from the intel drivers (non-kernel drivers).

Hi /home/kk,

Thank you for the additional information provided. I will check on this.rgds,wb

Hi /home/kk,

Good day. Further checking, we do not have information regarding the differences between our driver and the in-kernel driver as the in-kernel driver belong to the OS vendor which is beyond our supporting scope. You may refer to the URL below for the list of Intel drivers available https://sourceforge.net/projects/e1000/files/?source=navbarThanks,wb
