    net/smc: use worker to process incoming llc messages · 6c8968c4
    Karsten Graul authored
    Incoming llc messages are processed in irq tasklet context, and
    a worker is used to send outgoing messages. The worker is needed
    because getting a send buffer could result in a wait for a free buffer.
    
    To make sure all incoming llc messages are processed in a serialized way
    introduce an event queue and create a new queue entry for each message
    which is queued to this event queue. A new worker processes the event
    queue entries in order.
    And remove the use of a separate worker to send outgoing llc messages
    because the messages are processed in worker context already.
    With this event queue the serialized llc_wq work queue is obsolete,
    remove it.
