To: b.a.t.m.a.n
The requirement to have a VLAN master device on top of the batadv mesh
interface is artificially limiting the capabilities of batctl. Not all
master devices in linux which register a VLAN are from type "vlan" and are
only registering a single VLAN.
For example VLAN aware bridges can create multiple VLANs. These require
that the VLAN is identified using the VID and not the vlan device.

From: Sven Eckelmann @ 2019-06-23 13:07 UTC (permalink / raw)
To: b.a.t.m.a.n
batctl currently supports settings which are either mesh interface or vlan
specific. But B.A.T.M.A.N. V introduced two additional settings which are
hard (slave) interface specific.
To support these, an additional command prefix called hardif is implemented
for some sysfs commands:
$ batctl hardif eth0 ...
Alternative form is to use the prefix selector "slave"
$ batctl slave eth0 ...

B.A.T.M.A.N. V introduced a hard interface specific setting called
elp_interval. It defines the interval in milliseconds in which batman-adv
emits probing packets for neighbor sensing (ELP).

B.A.T.M.A.N. V introduced a hard interface specific setting called
throughput. It defines the throughput value to be used by B.A.T.M.A.N. V
when estimating the link throughput using this interface. If the value is
set to 0 then batman-adv will try to estimate the throughput by itself.

To: b.a.t.m.a.n
The '-m meshif' option doesn't follow the prefix style which is used for
VLANs/hard interfaces. It is also not clear for a user which command
understands the '-m' option and which is actually operating on a
global/non-meshif specific scope. To clean this up, an additional command
prefix called meshif is implemented:
$ batctl meshif bat0 ...
Alternative form is to use the prefix selector "dev"
$ batctl dev bat0 ...
This can be omitted when it would be "meshif bat0". And when it is
specified, all non-meshif specific subcommands will be rejected.
The old option '-m meshif' option is still available to avoid breaking
existing scripts. It will will show an error message but continues to work
for now. Users of batctl should still transition to the new format.

batctl allows three types of netdev based prefixes
* meshif <netdev>
* vlan <vdev>
* hardif <netdev>
The first word is used to tell batctl that the netdev is expected to be of
a specific type and all further information should be parsed in context of
this specific type. This avoids ambiguity when parsing the command line
information.
But there are various situations when there is no ambiguity at all. For all
of them, following points are true:
* <netdev|vdev> exists
* <netdev|vdev> has not the name of any existing batctl subcommand
* <netdev|vdev> is not "vlan", "vid", "hardif", "slave", "meshif" or "dev
In these situations, the first word can be omitted and batctl can guess the
type automatically.

Hi,
overall I think this is a good idea. Please see below:

I'd drop those alternative names "slave" and "dev". If we want to change the
naming, we have to do it everywhere. If we don't change the naming, then I
would say we shouldn't even advertise an alternative naming to not confuse
users and keep everything consistent. And if don't advertise, there is no good
reason to parse it and bloat the code.
That's my take, at least. :)
In general, I really like the tree like structure in favor of an unituitive
option parsing.
Cheers,
Simon
