      Revert "skge: fix ram buffer size calculation" · 279e1dab
      由 Linus Torvalds 提交于 
      This reverts commit 7fb7ac24.

Heikki Orsila reports that it causes a regression:

  "Doing

	nc host port < /dev/zero

   on a sending machine (not skge) to an skge machine that is receiving:

	nc -l -p port >/dev/null

   with ~60 MiB/s speed, causes the interface go malfunct. A slow
   transfer doesn't cause a problem."

See

	http://bugzilla.kernel.org/show_bug.cgi?id=9321

for some more information.

There is a workaround (also reported by Heikki):

  "After some fiddling, I noticed that not changing the register write
   order on patch:

   +       skge_write32(hw, RB_ADDR(q, RB_END), end);
           skge_write32(hw, RB_ADDR(q, RB_WP), start);
           skge_write32(hw, RB_ADDR(q, RB_RP), start);
   -       skge_write32(hw, RB_ADDR(q, RB_END), end);

   fixes the visible effect..  Possibly not the root cause of the
   problem, but changing the order back fixes networking here."

but that has yet to be ack'ed or tested more widely, so the whole
problem-causing commit gets reverted until this is resolved properly.

      [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.

      [NET]: Nuke SET_MODULE_OWNER macro. · 10d024c1
      由 Ralf Baechle 提交于 
      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.

      skge: set mac address bonding fix · 2eb3e621
      由 Stephen Hemminger 提交于 
      When bonding does fail over it calls set_mac_address.  When this happens
as the result of another port going down, the phy_mutex that is common to
both ports is held, so it deadlocks. Setting the address doesn't need to do
anything that needs the phy_mutex, it already has the RTNL to protect against
other admin actions.

This change just disables the receiver to avoid any hardware confusion
while address is changing.
