Hi Denis,

>> I am trying to plug 3 wifi dongle into one SBC(odroid c2 running armbian=
 22.01), wish to run separate iwd instance for each wifi dongle, in order t=
o connect different ssid and acquire dhcp ip address and assign to them.
>> I have successfully implement with systemd-networkd+vrf+iwd, assign thre=
e wifi dongle to different vrf. start iwd, all three wifi dongle could conn=
ect to the same ssid and get different ip with dhcp, including default rout=
e.
> =

> vrf?
> =

>> but when I assign different wifi dongle to the same ssid  with different=
 psk(my ap is aerohive, support ppsk, everything user have a different priv=
ate key. cisco, ruckus, aruba has such the same feature), iwd could not sav=
e the multiple config for the same ssid, because the same ssid share one co=
nfig. so any possible to run separate iwd for every wifi dongle?

> I don't think you'd be able to accomplish this easily with iwd as of toda=
y.  You can try running a private system bus (dbus) for each iwd instance a=
nd using phy filtering (see 'iwd --help') so that each iwd instance only ma=
nages the particular phy you want.  Or use namespaces.  But you'd need to a=
ccess each iwd instance via its private bus/namespace separately.  You'd al=
so need to override the state directory for each iwd instance.

you can use the environment variables STATE_DIRECTORY and CONFIGURATION_DIR=
ECTORY to point to separate directories for storage and config.

Regards

Marcel
