Similarly to the issue described in commit c52ae4057 (efinet: skip virtual IPv4 and IPv6 devices during card enumeration) the UEFI PXE driver creates additional VLAN child devices when a VLAN ID is configured on a network interface associated with a physical NIC. These virtual VLAN devices must be skipped during card enumeration to ensure that the subsequent SNP exclusive open operation targets the correct physical card instances. Otherwise packet transfer would fail. A device path example with VLAN nodes: /MAC(123456789ABC,0x1)/Vlan(20)/IPv4(0.0.0.0,0x0,DHCP,0.0.0.0,0.0.0.0,0.0.0.0) Signed-off-by: Michael Chang <mchang@suse.com> Reviewed-by: Daniel Kiper <daniel.kiper@oracle.com>
