  • 50ea05efa   mac80211: pass block ack session timeout to to driver ... Browse Code »

    Currently mac80211 does not inform the driver of the session
    block ack timeout when starting a rx aggregation session.
    Drivers that manage the reorder buffer need to know this
    parameter.
    Seeing that there are now too many arguments for the
    drv_ampdu_action() function, wrap them inside a structure.

  • 968a76cef   mac80211: call drv_stop only if driver is started ... Browse Code »

    If drv_start() fails during hw_restart, all the running
    interfaces are being closed/stopped, which results in
    drv_stop() being called, although the driver was never
    started successfully.

    This might cause drivers to perform operations on uninitialized
    memory (as they assume it was initialized on drv_start)

    Consider the local->started flag, and call the driver's stop()
    op only if drv_start() succeeded before.

    Move drv_start() and drv_stop() to driver-ops.c, as they are no
    longer simple wrappers.

    With this .config: http://busybox.net/~vda/kernel_config_ALLYES_Os,
    after deinlining these functions have sizes and callsite counts
    as follows:

    drv_get_tsf: 634 bytes, 6 calls
    drv_set_tsf: 626 bytes, 2 calls
    drv_reset_tsf: 617 bytes, 2 calls

    Total size reduction is about 4.2 kbytes.
