Hayes Wang e542a2269f r8169: adjust the RxConfig settings.
Set the init value before reset in probe function. And then just
modify the relative bits and keep the init settings.

For 8110S, 8110SB, and 8110SC series, the initial value of RxConfig
needs to be set after the tx/rx is enabled.

Hayes Wang 92fc43b415 r8169: modify the flow of the hw reset.
- 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.

Francois Romieu 56de414c0c r8169: remove non-NAPI context invocation of rtl8169_rx_interrupt.
Invocation of rtl8169_rx_interrupt from rtl8169_reset_task was originally
intended to retrieve as much packets as possible from the rx ring when a
reset was needed. Nowadays rtl8169_reset_task is only scheduled, with
some delay
a. from the tx timeout watchdog
b. when resuming
c. from rtl8169_rx_interrupt itself

It's dubious that the loss of outdated packets will matter much for a)
and b). c) does not need to call itself again.

Francois Romieu 4876cc1e49 r8169: link speed selection timer rework.
The implementation was a bit krusty.

The 10s rtl8169_phy_timer timer has been (was ?) required with older
8169 for adequate phy operation when full gigabit is advertised in
autonegotiated mode. The timer does nothing if the link is up.
Otherwise it keeps resetting the phy until things improve.

- the device private data field phy_1000_ctrl_reg was used to
  schedule the timer. Avoid it and save a few bytes.

- rtl8169_set_settings
  pending timer is disabled before changing the link settings as
  rtl8169_phy_timer is not always needed (see the removed test in
  rtl8169_phy_timer).

- rtl8169_set_speed
  the requested link parameters may not match the chipset : bail out
  early on failure.

- rtl8169_open
  Calling rtl8169_request_timer is redundant with
  -> rtl8169_open
     -> rtl8169_init_phy
        -> rtl8169_set_speed
           -> mod_timer
  The latter always enables the phy timer whereas the former did not
  for RTL_GIGA_MAC_VER_01. It should not make things worse but only
  time will tell if reality agrees.

- rtl8169_request_timer : unused yet. Removed.

- rtl8169_delete_timer : useless. Bloat. Removed.

Side effect : the timer may kick in if the TBI is enabled. I do not
know if the TBI has ever been used in real life.

Francois Romieu 826e6cbdad r8169: rtl8169_set_speed_xmii cleanup.
Shorten chipset version test.

No functional change.

Careful readers will notice that the 'supports_gmii' flag is deduced
from the device PCI id. Though less specific than the chipset related
RTL_GIGA_MAC_VER_XY, it is good enough to detect a GMII deprieved 810x.
Some features push for a device specific configuration (improved jumbo
frame support for instance). 'supports_gmii' will follow this path
if / when the device PCI id test stops working.

David Decotigny 7073949720 ethtool: cosmetic: Use ethtool ethtool_cmd_speed API
This updates the network drivers so that they don't access the
ethtool_cmd::speed field directly, but use ethtool_cmd_speed()
instead.

For most of the drivers, these changes are purely cosmetic and don't
fix any problem, such as for those 1GbE/10GbE drivers that indirectly
call their own ethtool get_settings()/mii_ethtool_gset(). The changes
are meant to enforce code consistency and provide robustness with
future larger throughputs, at the expense of a few CPU cycles for each
ethtool operation.

updated.

François Romieu 953a12cc28 r8169: don't request firmware when there's no userspace.
The firmware is cached during the first successfull call to open() and
released once the network device is unregistered. The driver uses the
cached firmware between open() and unregister_netdev().

So far the firmware is optional : a failure to load the firmware does
not prevent open() to success. It is thus necessary to 1) unregister
all 816x / 810[23] devices and 2) force a driver probe to issue a new
firmware load.

Francois Romieu 2b7b431858 r8169: TSO fixes.
- the MSS value is actually contained in a 11 bits wide (0x7ff) field.
  The extra bit in the former MSSMask did encompass the TSO command
  bit ("LargeSend") as well (0xfff). Oops.

- the Tx descriptor layout is not the same through the whole chipset
  family. The 8169 documentation, the 8168c documentation and Realtek's
  drivers (8.020.00, 1.019.00, 6.014.00) highlight two layouts:
  1. 8169, 8168 up to 8168b (included) and 8101
  2. {8102e, 8168c} and beyond

- notwithstanding the "first descriptor" and "last descriptor" bits, the
  same Tx descriptor content is enforced when a packet consists of several
  descriptors. The chipsets are documented to require it.

Francois Romieu f60ac8e7ab r8169: prevent RxFIFO induced loops in the irq handler.
While the RxFIFO interruption is masked for most 8168, nothing prevents
it to appear in the irq status word. This is no excuse to crash.

Francois Romieu 1519e57fe8 r8169: RxFIFO overflow oddities with 8168 chipsets.
Some experiment-based action to prevent my 8168 chipsets locking-up hard
in the irq handler under load (pktgen ~1Mpps). Apparently a reset is not
always mandatory (is it at all ?).

- RTL_GIGA_MAC_VER_12
- RTL_GIGA_MAC_VER_25
  Missed ~55% packets. Note:
  - this is an old SiS 965L motherboard
  - the 8168 chipset emits (lots of) control frames towards the sender

- RTL_GIGA_MAC_VER_26
  The chipset does not go into a frenzy of mac control pause when it
  crashes yet but it can still be crashed. It needs more work.
