All,
I've been help development a DPDK application that (mainly) runs on dedicated
hardware (i40e NICS), Intel CPUs. However, we have been asked to see if this can
be run in the ESXi (VMware) environment. This seemed fine as we have the VMXNET3
PMD and aside from some missing features, it seemed to work.
Until we tried to down the port, using rte_eth_dev_set_down() API. This API is
returning -95 (EOPNOTSUPP) which I take to mean that its link state cannot be
changed.
Sorry, I mistakenly put the incorrect function name. I meant
rte_eth_dev_set_link_down().

I checked the PMD documentation for this driver and cannot find any mention that
this is a limitation.
I've never looked at the linux implementation (which our older, pre-DPDK) uses
but it allows the interface to be marked down.
Is my only work-around to stop the device instead?
Thanks for any wisdom...
