Difference between vlan pseudo interfaces and physical interfaces?

[Hauke Fath <hauke%Espresso.Rhein-Neckar.DE@localhost>]

Hi,

are there any differences in application between vlans and physical 
network interfaces when it comes to non-IP protocols?

I just rototilled my home network for a vlan capable switch, and found 
that the Netatalk 2 atalkd refuses to work with vlan interfaces:

# kdump
[...]
 19528      1 atalkd   CALL  ioctl(4,SIOCGIFADDR,0x7f7fffdbb950)
 19528      1 atalkd   GIO   fd 4 wrote 144 bytes
       
"vlan11\0\0\240h\M-}\M-Q\^Cs\0\0\M^@p\M^@\M-Q\^Cs\0\0\M-VV\M--\M-Q\^Cs\0\0\M^H\M-9\M-[\M^?\^?\^?\0\0\0\^P\0\0\0\0\0\0\M-8\^^I\M-Q\^Cs\0\0\M-8\^^I\M-Q\^Cs\0\0\^A\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\
        
\^A\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\^A\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\^A\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\^A\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"
 19528      1 atalkd   RET   ioctl -1 errno 49 Can't assign requested 
address
[...]

-- is atalkd being too picky here, or is there a fundamental 
incompatibility for ddp packets?

Cheerio,
Hauke
