This patch adds vlan range support to bridge add command
using the newly added vinfo flags BRIDGE_VLAN_INFO_RANGE_BEGIN and
BRIDGE_VLAN_INFO_RANGE_END.

$bridge vlan show
port    vlan ids
br0      1 PVID Egress Untagged

dummy0   1 PVID Egress Untagged

$bridge vlan add vid 10-15 dev dummy0
port    vlan ids
br0      1 PVID Egress Untagged

dummy0   1 PVID Egress Untagged
         10
         11
         12
         13
         14
         15

$bridge vlan del vid 14 dev dummy0

$bridge vlan show
port    vlan ids
br0      1 PVID Egress Untagged

dummy0   1 PVID Egress Untagged
         10
