netdevsim: Make nsim_num_vf static

2019-05-05T17:48:45+00:00

Fix sparse warning:

drivers/net/netdevsim/bus.c:253:5: warning:
 symbol 'nsim_num_vf' was not declared. Should it be static?

netdevsim: fix fall-through annotation

2019-05-01T15:36:55+00:00

Replace "pass through" with a proper "fall through" annotation
in order to fix the following warning:

drivers/net/netdevsim/bus.c: In function ‘new_device_store’:
drivers/net/netdevsim/bus.c:170:14: warning: this statement may fall through [-Wimplicit-fallthrough=]
   port_count = 1;
   ~~~~~~~~~~~^~~
drivers/net/netdevsim/bus.c:172:2: note: here
  case 2:
  ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

This fix is part of the ongoing efforts to enable
-Wimplicit-fallthrough

netdevsim: move netdev creation/destruction to dev probe

2019-04-26T05:52:03+00:00

Remove the existing way to create netdevsim over rtnetlink and move the
netdev creation/destruction to dev probe, so for every probed port,
a netdevsim-netdev instance is created.

Adjust selftests to work with new interface.

netdevsim: extend device attrs to support port addition and deletion

2019-04-26T05:52:03+00:00

In order to test flows in core, it is beneficial to maintain previously
supported possibility to add and delete ports during netdevsim lifetime.
Do it by extending device sysfs attrs by "new_port" and "del_port".

netdevsim: implement dev probe/remove skeleton with port initialization

2019-04-26T05:52:02+00:00

Implement netdevsim bus probing of netdevsim devices. For every probed
device create a devlink instance. According to the user-passed value,
create a number of ports represented by devlink port instances.

netdevsim: add bus attributes to add new and delete devices

2019-04-26T05:52:02+00:00

Add a way to add new netdevsim device on netdevsim bus and also to
delete existing netdevsim device from the bus. Track the bus devices
in using a list.

netdevsim: use ida for bus device ids

2019-04-26T05:52:02+00:00

Instead of increments of u32 value, use ida to manage bus device ids.

netdevsim: add stub netdevsim driver implementation

2019-04-26T05:52:02+00:00

In order to bus probing to work correctly, register a simple  netdevsim
driver implementation.

netdevsim: move device registration and related code to bus.c

2019-04-26T05:52:02+00:00

Move netdevsim device registration into bus.c and alongside with that
the related sysfs attributes. Introduce new struct nsim_bus_dev to
represent a netdevsim device on netdevsim bus.

netdevsim: put netdevsim bus code into separate file

2019-04-26T05:52:02+00:00

As the code related to netdevsim bus is going to get bigger, move the
existing code to a separate file.
