Sorry, the other way around: you need to lower the vlan4's MTU by 4 on creation. I'd assume that "ifconfig vlan4 create vlandev cpsw0 mtu 1496" would do the trick. >> Afterward, the VLAN interface does exist, but with wrong lladdr, >> "status: no carrier" (even though the parent is active), and it seems >> not possible to assign an inet address on the VLAN interface either: >> >> # ifconfig vlan4 >> vlan4: flags=8003<UP,BROADCAST,MULTICAST> mtu 1500 >> lladdr 00:00:00:00:00:00 >> index 8 priority 0 llprio 3 >> vlan: 4 parent interface: cpsw0 >> vnetid: 4 >> parent: cpsw0 >> groups: vlan >> status: no carrier >> >> dmesg follows, thank you. >> >> OpenBSD 6.0 (GENERIC) #286: Thu Jul 28 12:33:51 AEST 2016 >> j...@armv7.jsg.id.au:/usr/src/sys/arch/armv7/compile/GENERIC >> real mem = 536870912 (512MB) >> avail mem = 518017024 (494MB) >> mainbus0 at root: TI AM335x BeagleBone Black >> cpu0 at mainbus0: ARM Cortex A8 R3 rev 2 (ARMv7 core) >> cpu0: DC enabled IC enabled WB disabled EABT branch prediction enabled >> cpu0: 32KB(64b/l,4way) I-cache, 32KB(64b/l,4way) wr-back D-cache >> omap0 at mainbus0 >> prcm0 at omap0 rev 0.2 >> sitaracm0 at omap0: control module, rev 1.0 >> intc0 at omap0 rev 5.0 >> edma0 at omap0 rev 0.0 >> dmtimer0 at omap0 rev 3.1 >> dmtimer1 at omap0 rev 3.1 >> omgpio0 at omap0: rev 0.1 >> gpio0 at omgpio0: 32 pins >> omgpio1 at omap0: rev 0.1 >> gpio1 at omgpio1: 32 pins >> omgpio2 at omap0: rev 0.1 >> gpio2 at omgpio2: 32 pins >> omgpio3 at omap0: rev 0.1 >> gpio3 at omgpio3: 32 pins >> simplebus0 at mainbus0: "ocp" >> simplebus1 at simplebus0: "l4_wkup" >> simplebus2 at simplebus1: "scm" >> com0 at simplebus0: ti16750, 64 byte fifo >> com0: console >> tiiic0 at simplebus0 rev 0.11 >> iic0 at tiiic0 >> "ti,tps65217" at iic0 addr 0x24 not configured >> "at,24c256" at iic0 addr 0x50 not configured >> "nxp,tda998x" at iic0 addr 0x70 not configured >> tiiic1 at simplebus0 rev 0.11 >> iic1 at tiiic1 >> "at,24c256" at iic1 addr 0x54 not configured >> "at,24c256" at iic1 addr 0x55 not configured >> "at,24c256" at iic1 addr 0x56 not configured >> "at,24c256" at iic1 addr 0x57 not configured >> ommmc0 at simplebus0 >> sdmmc0 at ommmc0: 1-bit, mmc high-speed >> ommmc1 at simplebus0 >> sdmmc1 at ommmc1: 1-bit, mmc high-speed >> omdog0 at simplebus0 rev 0.1 >> cpsw0 at simplebus0: version 1.12 (0), address d0:39:72:37:8a:d3 >> ukphy0 at cpsw0 phy 0: Generic IEEE 802.3u media interface, rev. 1: OUI >> 0x0001f0, model 0x000f >> sdmmc0: can't enable card >> scsibus0 at sdmmc1: 2 targets, initiator 0 >> sd0 at scsibus0 targ 1 lun 0: <Kingston, MMC04G, 0000> SCSI2 0/direct fixed >> sd0: 3688MB, 512 bytes/sector, 7553024 sectors >> vscsi0 at root >> scsibus1 at vscsi0: 256 targets >> softraid0 at root >> scsibus2 at softraid0: 256 targets >> boot device: sd0 >> root on sd0a (3d49b2642530c3a2.a) swap on sd0b dump on sd0b >> WARNING: CHECK AND RESET THE DATE! >> >> -- >> Steven Chamberlain >> ste...@pyro.eu.org >>
