stmmac: fix missing MODULE_LICENSE in stmmac_platform

2015-07-31T22:44:24+00:00

Commit 50649ab14982 ("stmmac: drop driver from stmmac platform code")
was a bit overzealous in removing code and dropped the MODULE_*
macro's that are still needed since stmmac_platform can be a module.
Fix this by putting the macro's remvoed in 50649ab14982 back.

This fixes the following errors when used as a module:
  stmmac_platform: module license 'unspecified' taints kernel.
  Disabling lock debugging due to kernel taint
  stmmac_platform: Unknown symbol devm_kmalloc (err 0)
  stmmac_platform: Unknown symbol stmmac_suspend (err 0)
  stmmac_platform: Unknown symbol platform_get_irq_byname (err 0)
  stmmac_platform: Unknown symbol stmmac_dvr_remove (err 0)
  stmmac_platform: Unknown symbol platform_get_resource (err 0)

gianfar: Enable device wakeup when appropriate

2015-07-31T22:41:49+00:00

The wol_en flag is 0 by default anyway, and we have the
following inconsistency: a MAGIC packet wol capable eth
interface is registered as a wake-up source but unable
to wake-up the system as wol_en is 0 (wake-on flag set to 'd').
Calling set_wakeup_enable() at netdev open is just redundant
because wol_en is 0 by default.
Let only ethtool call set_wakeup_enable() for now.

The bflock is obviously obsoleted, its utility has been corroded
over time.  The bitfield flags used today in gianfar are accessed
only on the init/ config path, with no real possibility of
concurrency - nothing that would justify smth. like bflock.

gianfar: Fix suspend/resume for wol magic packet

2015-07-31T22:41:49+00:00

If we disable NAPI in the first place we can mask the device's
interrupts (and halt it) without fearing that imask may be
concurrently accessed from interrupt context, so there's
no need to do local_irq_save() around gfar_halt_nodisable().
lock_rx_qs()/unlock_tx_qs() are just obsoleted and potentially
buggy routines.  The txlock is currently used in the driver only
to manage TX congestion, it has nothing to do with halting the
device.  With these changes, the TX processing is stopped before
gfar_halt().

Compact gfar_halt() is used instead of gfar_halt_nodisable(),
as it disables Rx/TX DMA h/w blocks and the Rx/TX h/w queues.
gfar_start() re-enables all these blocks on resume.  Enabling
the magic-packet mode remains the same, note that the RX block
is re-enabled just before entering sleep mode.

Add IRQF_NO_SUSPEND flag for the error interrupt line, to signal
that the interrupt line must remain active during sleep in order
to wake the system by magic packet (MAG) reception interrupt.
(On some systems the MAG interrupt did trigger w/o this flag
as well, but on others it didn't.)

Without these fixes, when suspended during fair Tx traffic the
interface occasionally failed to be woken up by magic packet.

2015-07-30T21:03:46+00:00

Add rtl8152_pre_reset() and rtl8152_post_reset() which are used when
calling usb_reset_device(). The two functions could reduce the time
of reset when calling usb_reset_device() after probe().

This fixes a crash when changing rss with multiple traffic flows.

While interface teardown, disable tx queues after all NAPI threads
are done. If done otherwise tx queues might be woken up inside NAPI
if any CQE_TX are processed.
