      Unknown 8168 chips did not have any PLL power method set as they

      r8169: merge firmware information into the chipset description data. · 85bffe6c
      由 Francois Romieu 提交于 
      - RTL_GIGA_MAC_NONE is a fake index so put it at the end of the
  enumeration and shift everybody.
- RTL_GIGA_MAC_VER_17 / RTL_GIGA_MAC_VER_16 ordering fixed. Though
  not wrong it was confusing enough to wonder if things were right.

Renaming rtl_chip_info was not strictly necessary. It allows to
check the patch for the correct use of the indexes though.

      r8169: remove non-NAPI context invocation of rtl8169_rx_interrupt. · 56de414c
      由 Francois Romieu 提交于 
      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It's dubious that the loss of outdated packets will matter much for a)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.

      r8169: link speed selection timer rework. · 4876cc1e
      由 Francois Romieu 提交于 
      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.

      r8169: rtl8169_set_speed_xmii cleanup. · 826e6cbd
      由 Francois Romieu 提交于 
      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.

      r8169: TSO fixes. · 2b7b4318
      由 Francois Romieu 提交于 
      - 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.
