      net/ehea: bitops work on unsigned longs · 48e4cc77
      由 Stephen Rothwell 提交于 
      The flags field of struct ehea_port is only used with test_bit(),
clear_bit() and set_bit() and these interfaces only work on
"unsigned long"s, so change the field to be an "unsigned long".  Also,
this field only has two bits defined for it (0 and 1) so will still be
fine if someone builds this driver for a 32 bit arch (at least as far as
this flags field is concerned).

Also note that ehea_driver_flags is only used in ehca_main.c, so make it
static in there.

      ehea: add kdump support · 21eee2dd
      由 Thomas Klein 提交于 
      This patch adds kdump support to the ehea driver. As the firmware doesn't free
resource handles automatically, the driver has to run an as simple as possible
free resource function in case of a crash shutdown. The function iterates over
two arrays freeing all resource handles which are stored there. The arrays are
kept up-to-date during normal runtime. The crash handler fn is triggered by the
recently introduced PPC crash shutdown reg/unreg functions.

      [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.

[ Ported to current tree and all drivers converted.  Integrated
  Stephen's follow-on kerneldoc additions, and restored poll_list
  handling to the old style to fix mutual exclusion issues.  -DaveM ]

      ehea: propagate physical port state · 8759cf76
      由 Jan-Bernd Themann 提交于 
      Introduces a module parameter to decide whether the physical
port link state is propagated to the network stack or not.
It makes sense not to take the physical port state into account
on machines with more logical partitions that communicate
with each other. This is always possible no matter what the physical
port state is. Thus eHEA can be considered as a switch there.

      eHEA: Fix bonding support · f9e29228
      由 Thomas Klein 提交于 
      The driver didn't allow an interface's MAC address to be modified if the
respective interface wasn't setup - a failing Hcall was the result. Thus
bonding wasn't usable. The fix moves the failing Hcall which was registering
a MAC address for the reception of BC packets in firmware from the port up
and down functions to the port resources setup functions. Additionally the
missing update of the last_rx member of the netdev structure was added.

      eHEA: Introducing support vor DLPAR memory add · 44c82152
      由 Thomas Klein 提交于 
      This patch adds support for DLPAR memory add to the eHEA driver. To detect
whether memory was added the driver uses its own memory mapping table and
checks for kernel addresses whether they're located in already known memory
sections. If not the function ehea_rereg_mrs() is triggered which performs
a rebuild of the mapping table and a re-registration of the global memory
region.
