Hi Greg,
Upstream commit 028daf801173 ("i40e: Fix attach VF to VM issue")
fixes a virtualization issue for i40e based adapters.
problem description below from the commit:
'Fix for "Resource temporarily unavailable" problem when virsh is
trying to attach a device to VM. When the VF driver is loaded on
host and virsh is trying to attach it to the VM and set a MAC
address, it ends with a race condition between i40e_reset_vf and
i40e_ndo_set_vf_mac functions. The bug is fixed by adding polling
in i40e_ndo_set_vf_mac function For when the VF is in Reset mode.'
Please apply commit 028daf801173 to fix the resulting regression.
Thanks,
Sinan
