      [TG3]: Fix tg3_restart_ints() · 04237ddd
      由 Michael Chan 提交于 
      tg3_restart_ints() is called to re-enable interrupts after tg3_poll()
has finished all the work. It calls tg3_cond_int() to force an interrupt
if the status block updated bit is set. The updated bit will be set if
there is a new status block update sometime during tg3_poll() and it can
be very often. The worst part is that even if all the work has been
processed, the updated bit remains set and an interrupt will be forced
unnecessarily.

The fix is to call tg3_has_work() instead to determine if new work is
posted before forcing an interrupt. The way to force an interrupt is
also changed to use "coalesce_now" instead of "SETINT". The former is
generally a safer way to force the interrupt.

Also deleted the first parameter to tg3_has_work() which is unused.

      [TG3]: Refresh hw index in tg3_rx() · 52f6d697
      由 Michael Chan 提交于 
      This patch refreshes the hw rx producer in tg3_rx() so that additional
work posted by the hardware can be processed.

      [TG3]: Fix bug in tg3_rx() · 483ba50b
      由 Michael Chan 提交于 
      This patch fixes a bug that causes tg3_has_work() to always return 1.

rx work is determined by comparing tp->rx_rcb_ptr with the current hw
producer index. The hw producer index is modulo the ring size, but tp-
>rx_rcb_ptr is a free running counter that goes up beyond the ring size.
After the ring wraps around once, tg3_has_work() will always return 1.

The fix is to always do modulo arithmetic on tp->rx_rcb_ptr.

      [PATCH] usb suspend updates (interface suspend) · 27d72e85
      由 David Brownell 提交于 
      This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t".  This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:

    - <linux/usb.h> and usbcore, signature change

    - Some drivers only changed the signature, net effect this just
      shuts up "sparse -Wbitwise":
	* hid-core
	* stir4200

    - Two network drivers did that, and also grew slightly more
      featureful suspend code ... they now properly shut down
      their activities.  (As should stir4200...)
	* pegasus
	* usbnet

Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.
