- Disable tx and rx by resetting hw, so replace rtl8169_asic_down
  with rtl8169_hw_reset.
- RxConfig bits 0 ~ 5 have to be cleared before hw reset to avoid
  receiving spurious data.
- Certain chips need to do some checking before reset.
- Remove hw reset which is done before hw_start. It is done in close,
  down or device probe functions.
- Move rtl8169_init_ring_indexes function into rtl_hw_reset function.
  The indexes of tx and rx only need to be zero when the hw resets.

This is a backport from the vendor driver of support for the newer Optima
(Prime and 2) chipsets. It also includes some setup changes for the
current Optima chip as well. The code and comments intentionally
mirror the vendor sk98lin driver to allow for easier maintenance.

Although this adds support for new chip id's, these chip id's are not
used by any of the current PCI device id's listed in the driver.
The patch is just to get initial infrastructure in place to handle them
when they come.

Implementing this callback function will cause mac80211 refrain from
going to powersave state when there are still untransmitted TX frames
in the queues.
This would exactly mimic the behaviour of the legacy vendor driver which
also doesn't go in powersave mode if there are still TX frames that are not
transmitted.
This should make powersaving and rt2x00 a better couple.

The functions that create the tx descriptor structure do not operate on
a queue entry at all. Signal this fact in the code by not providing a
queue entry as a parameter, but the rt2x00 device structure and the skb
directly.

This patch is a preparation for reducing the time a queue is locked for
a tx operation.

The rt2x00 driver gets frequent occurrences of the following error message
when operating under load:
phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the
non-full queue 2.

This is caused by simultaneous attempts from mac80211 to send a frame via
rt2x00, which are not properly serialized inside rt2x00queue_write_tx_frame,
causing the second frame to fail sending with the above mentioned error
message.

Fix this by introducing a per-queue spinlock to serialize the TX operations
on that queue.

This patch adds userspace buffers support in skb shared info. A new
struct skb_ubuf_info is needed to maintain the userspace buffers
argument and index, a callback is used to notify userspace to release
the buffers once lower device has done DMA (Last reference to that skb
has gone).

If there is any userspace apps to reference these userspace buffers,
then these userspaces buffers will be copied into kernel. This way we
can prevent userspace apps from holding these userspace buffers too long.

Use destructor_arg to point to the userspace buffer info; a new tx flags
SKBTX_DEV_ZEROCOPY is added for zero-copy buffer check.
