[ipxe-devel] Question about efi_snp.c

[Deep ML]

Hello,

I have a question about the efi_snp.c code. We are using ipxe in a Qemu/KVM
VM with OVMF firmware. The underlying hardware NIC is Intel 82599 10 Gb and
the VM is configured to use it through vfio-pci.

When the VM boots, the efi_snp_receive function in efi_snp.c gets called
multiple times, before ipxe "claims" the net device. What is this polling
useful for, when we are using ipxe with OVMF?

Thanks.
