      r8169: avoid thrashing PCI conf space above RTL_GIGA_MAC_VER_06 · 77332894
      由 Marcus Sundberg 提交于 
      The magic write to register 0x82 will often cause PCI config space on
my 8168 (PCI ID 10ec:8168, revision 2. mounted in an LG P300 laptop)
to be filled with ones during driver load, and thus breaking NIC
operation until reboot. If it does not happen on first driver load it
can easily be reproduced by unloading and loading the driver a few
times.

The magic write was added long ago by this commit:

Author: François Romieu <romieu@fr.zoreil.com>
Date:   Sat Jan 10 06:00:46 2004 -0500

     [netdrvr r8169] Merge of changes done by Realtek to rtl8169_init_one():
     - phy capability settings allows lower or equal capability as suggested
       in Realtek's changes;
     - I/O voodoo;
     - no need to s/mdio_write/RTL8169_WRITE_GMII_REG/;
     - s/rtl8169_hw_PHY_config/rtl8169_hw_phy_config/;
     - rtl8169_hw_phy_config(): ad-hoc struct "phy_magic" to limit duplication
       of code (yep, the u16 -> int conversions should work as expected);
     - variable renames and whitepace changes ignored.

As the 8168 wasn't supported by that version this patch simply removes
the bogus write from mac versions <= RTL_GIGA_MAC_VER_06.

[The change above makes sense for the 8101/8102 too -- Ueimor]

      r8169: multicast register update · f887cce8
      由 Francois Romieu 提交于 
      The layout of the 8101 series is identical to that of the 8168 one,
thus allowing to pack everything not 8169 related above MAC_VER_06.
New 810x and 8168 chipsets should automagically behave correctly.

It matches code in Realtek's 1.008.00 8101 and 8.007.00 8168 drivers.

      [NET]: Fix drivers to handle napi_disable() disabling interrupts. · d1d08d12
      由 David S. Miller 提交于 
      When we add the generic napi_disable_pending() breakout
logic to net_rx_action() it means that napi_disable()
can cause NAPI poll interrupt events to be disabled.

And this is exactly what we want.  If a napi_disable()
is pending, and we are looping in the ->poll(), we want
->poll() event interrupts to stay disabled and we want
to complete the NAPI poll ASAP.

When ->poll() break out during device down was being handled on a
per-driver basis, often these drivers would turn interrupts back on
when '!netif_running()' was detected.

And this would just cause a reschedule of the NAPI ->poll() in the
interrupt handler before the napi_disable() could get in there and
grab the NAPI_STATE_SCHED bit.

The vast majority of drivers don't care if napi_disable() might have
the side effect of disabling NAPI ->poll() event interrupts.  In all
such cases, when a napi_disable() is performed, the driver just
disabled interrupts or is about to.

However there were three exceptions to this in PCNET32, R8169, and
SKY2.  To fix those cases, at the subsequent napi_enable() points, I
added code to ensure that the ->poll() interrupt events are enabled in
the hardware.

      [ETHTOOL] Provide default behaviors for a few ethtool sub-ioctls · 88d3aafd
      由 Jeff Garzik 提交于 
      For the operations
	get-tx-csum
	get-sg
	get-tso
	get-ufo
the default ethtool_op_xxx behavior is fine for all drivers, so we
permit op==NULL to imply the default behavior.

This provides a more uniform behavior across all drivers, eliminating
ethtool(8) "ioctl not supported" errors on older drivers that had
not been updated for the latest sub-ioctls.

The ethtool_op_xxx() functions are left exported, in case anyone
wishes to call them directly from a driver-private implementation --
a not-uncommon case.  Should an ethtool_op_xxx() helper remain unused
for a while, except by net/core/ethtool.c, we can un-export it at a
later date.

      It's been a useless no-op for long enough in 2.6 so I figured it's time to
remove it.  The number of people that could object because they're
maintaining unified 2.4 and 2.6 drivers is probably rather small.

      [NET]: Make NAPI polling independent of struct net_device objects. · bea3348e
      由 Stephen Hemminger 提交于 
      Several devices have multiple independant RX queues per net
device, and some have a single interrupt doorbell for several
queues.

In either case, it's easier to support layouts like that if the
structure representing the poll is independant from the net
device itself.

The signature of the ->poll() call back goes from:

	int foo_poll(struct net_device *dev, int *budget)

to

	int foo_poll(struct napi_struct *napi, int budget)

The caller is returned the number of RX packets processed (or
the number of "NAPI credits" consumed if you want to get
abstract).  The callee no longer messes around bumping
dev->quota, *budget, etc. because that is all handled in the
caller upon return.

The napi_struct is to be embedded in the device driver private data
structures.

Furthermore, it is the driver's responsibility to disable all NAPI
instances in it's ->stop() device close handler.  Since the
napi_struct is privatized into the driver's private data structures,
only the driver knows how to get at all of the napi_struct instances
it may have per-device.

With lots of help and suggestions from Rusty Russell, Roland Dreier,
Michael Chan, Jeff Garzik, and Jamal Hadi Salim.

Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra,
Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan.

It uses RTL_GIGA_MAC_VER_05 and this part of the changeset can cut
its performance by a factor of 2~2.5 as reported by Timo.

register when mac_version == RTL_GIGA_MAC_VER_0[1-4])
