Subject: [PATCH] mlxsw: minimal: Add interfaces for line card initialization
|
|
and de-initialization
|
|
|
|
Add callback functions for line card 'netdevice' objects initialization
|
|
and de-initialization. Each line card is associated with the set of
|
|
'netdevices', which are created/destroyed dynamically, when line card
|
|
is getting to active / inactive states.
|
|
|
|
Add APIs for line card registration and de-registration during init and
|
|
de-init.
|
|
