Hi,

While trying to enable SR-IOV for a fresh install of Proxmox 7.2 in Dell R7525, it is found that the NIC driver is not exposing sriov_numvfs in /sys/class/net/eno33/device. Please Help..

can you also post the output of 'lspci -vvv' ?
sometimes vendors (e.g. dell) rebrands those cards and do not enable all features in the firmware. e.g. we have a few I350-T2 here and not all are capable of SR-IOV (but some are)

What you said is correct... !!!!!
Dell has not enabled SR-IOV in the NIC firmware as lspci is not listing it as a capability...
Thanks a lot for the pointer.

We will contact dell about this...

Is it possible for us to upgrade the firmware ourselves ?? Will it void the warranty ??

Hi dcsapak

It was not a Dell mistake, rather lack of my patience. For a 128 core mammoth, it doesn't make sense not to provide a NIC with SR-IOV enabled when BIOS have a global SR-IOV enable setting.

In my attempt to contact Dell, after sending an initial email, I was roaming around in the BIOS for reporting the current NIC firmware for Intel X710T2L NIC.... There deep inside a setting was hiding where I should enable SR-IOV for the NIC.

Once enabled, I could get sriov_numvfs in /sys/class/net/eno33/device


Bash:

root@veena2:~# cd /sys/class/net/eno33/device/
root@veena2:/sys/class/net/eno33/device#

sriov_drivers_autoprobe  sriov_numvfs  sriov_offset  sriov_stride  sriov_totalvfs  sriov_vf_device  sriov_vf_total_msix

See above that SR-IOV capability is advertised.

Sorry for suspecting Dell for my mistake.

great that it works now.

regardless if it is enabled on this model, there are cases where dell/hp/etc. disable such features, for whatever reason...

For same model having differently featured exact h/w NIC is rather surprising !!! and rationale rather puzzling.. Did a firmware upgrade worked for you to solve the issue ? Did those companies provided them or you did at your own risk ??

But differently priced models differentiated based on selective feature disable is common in consumer products. For example one famous japanese camera company whom i had worked for, have same SOC inside their most expensive and least expensive cameras with almost same firmware. Only features are enabled or disabled based on CMOS sensors, other sensors and pricing. In short, from electronics point of view their product cost are the same, while the look, feel, experience and pricing vary vastly.
