1) SRIOV guest KMD doesn't care training buffer
2) if we resered training buffer that will overlap with IP discovery
reservation because training buffer is at vram_size - 0x8000 and
IP discovery is at ()vram_size - 0x10000 => vram_size -1)

Missing { } here, apart from that the series looks good to me.
