Subject: [PATCH 12/15] misc: nnpi: Route device response messages
Route both types of messages coming from the NNP-I card - event
report messages, which are handled by the driver, and command-response
messages, which should be routed to a specific command channel object
("channel").
Event report messages are device-level messages which are not
associated with a specific channel. They are typically initiated by the
NNP-I card, to indicate an error, status change, or any event which
is not a response to a message sent from a spcific channel. These event
report messages are handled by the driver.
In contrast, command-response messages are associated with a specific
channel, and are typically sent from the NNP-I card in response to a
message sent from a channel to the card. These command-response
messages are added to the intended channel ring-buffer for consumption
by this channel.
The list of messages, of both types, coming from the card, is defined
in ipc_include/ipc_c2h_events.h included in this patch.
