Subject: [PATCH v4 net-next 09/11] net/nebula-matrix: add Dispatch layer implementation
This patch can have a quick review, function is similar
The primary issue in the Dispatch layer is how to determine
the routing approach
Two routing ways:
Dispatch Layer-> Resource Layer -> HW layer
The Dispatch Layer routes tasks to Resource Layer, which may interact
with the HW Layer for hardware writes.
Dispatch Layer->Channel Layer
The Dispatch Layers redirects hooks to the Channel Layer.
The primary challenge at the Dispatch layer lies in determining the
routing approach, namely, how to decide which interfaces should directly
invoke the Resource layer's interfaces and which should transmit
requests via channels to the management PF for processing.
To address this, a ctrl_lvl (control level) mechanism is established,
which comprises two parts: the control level declared by each interface
and the control level configured by the upper layer. The effect is that
when the upper layer configures a specific control level, all interfaces
declaring this level will directly call the Resource layer's interfaces;
otherwise, they will send requests via channels.
For instance, consider a regular PF that possesses network (net)
capabilities but lacks control (ctrl) capabilities. It will only
configure NET_LVL at the Dispatch layer. In this scenario, all
interfaces declaring NET_LVL will directly invoke the Resource layer's
interfaces, while those declaring CTRL_LVL will send requests via
channels to the management PF. Conversely, if it is the management PF,
it will configure both NET_LVL and CTRL_LVL at the Dispatch layer.
Consequently, interfaces declaring CTRL_LVL will also directly call the
Resource layer's interfaces without sending requests via channels. This
configuration logic can be dynamic.(nbl_disp_setup_ctrl_lvl)
