Currently, despite the comment right before the function,
nf_log_register allows registering two loggers on with the same type and
end up overwriting the previous register.

Not a real issue today as current tree doesn't have two loggers for the
same type but it's better to get this protected.

Also make sure that all of its callers do error checking.

A full Rx ring only requires 1 MiB of memory.  This is not enough
memory that it is useful to dynamically scale the number of Rx
requests in the ring based on traffic rates, because:

a) Even the full 1 MiB is a tiny fraction of a typically modern Linux
   VM (for example, the AWS micro instance still has 1 GiB of memory).

b) Netfront would have used up to 1 MiB already even with moderate
   data rates (there was no adjustment of target based on memory
   pressure).

c) Small VMs are going to typically have one VCPU and hence only one
   queue.

Keeping the ring full of Rx requests handles bursty traffic better
than trying to converge on an optimal number of requests to keep
filled.

On a 4 core host, an iperf -P 64 -t 60 run from dom0 to a 4 VCPU guest
improved from 5.1 Gbit/s to 5.6 Gbit/s.  Gains with more bursty
traffic are expected to be higher.

sunvnet: NAPIfy sunvnet

This patchset converts the sunvnet driver to use the NAPI framework.
Changes since v4 to Patch1:
  vnet_event accumulates LDC_EVENT_* bits into rx_event.
  vnet_event_napi() unrolls send_events() logic to process all rx_event bits.
Changes since v5:
  Patch 1: use net_device.h definition for NAPI_POLL_WEIGHT.
  Drop sparclinux changes (patch3) per David Miller feedback

Patch 1 in the series addresses the packet-receive path- all
the vnet_event() processing is moved into NAPI context.
This patch is dependant on the sparc-next commit:
  "sparc64: Add vio_set_intr() to enable/disable Rx interrupts"
  (sparc commit id ca605b7d)

Patch 2 uses RCU to fix race conditions between vnet_port_remove and
paths that access/modify port-related state, such as vnet_start_xmit.

Patch 3 leverages from the NAPIfied Rx path,
dropping superfluous usage of the irqsave/irqrestores on the vio.lock
where possible.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

After the  NAPIfication of sunvnet, we no longer need to
synchronize by doing irqsave/restore on vio.lock in the
I/O fastpath.

NAPI ->poll() is non-reentrant, so all RX processing occurs
strictly in a serialized environment. TX reclaim is done in NAPI
context, so the netif_tx_lock can be used to serialize
critical sections between Tx and Rx paths.

A vnet_port_remove could be triggered as a result of an ldm-unbind
operation by the peer, module unload, or other changes to the
inter-vnet-link configuration.  When this is concurrent with
vnet_start_xmit(), there are several race sequences possible,
such as

thread 1                                    thread 2
vnet_start_xmit
-> tx_port_find
   spin_lock_irqsave(&vp->lock..)
   ret = __tx_port_find(..)
   spin_lock_irqrestore(&vp->lock..)
                                           vio_remove -> ..
                                               ->vnet_port_remove
                                           spin_lock_irqsave(&vp->lock..)
                                           cleanup
                                           spin_lock_irqrestore(&vp->lock..)
                                           kfree(port)

This patch adds RCU locking for port access so that vnet_port_remove

Move Rx packet procssing to the NAPI poll callback.
Disable VIO interrupt and unconditioanlly go into NAPI
context from vnet_event.

Note that we want to minimize the number of LDC
STOP/START messages sent. Specifically, do not send a STOP
message if vnet_walk_rx does not read all the available descriptors
because of the NAPI budget limitation. Instead, note the end index
as part of port state, and resume from this index when the
next poll callback is triggered.

Intel Wired LAN Driver Updates 2014-10-23

This series contains updates to i40e and i40evf.

Jesse modifies the i40e driver to only notify the firmware on link up/down
and qualified module events.  Also simplified the job of managing link
state by using the admin queue receive event for link events as a signal
to tell the driver to update link state.

Jeff (me) cleans up the inconsistent use of tabs for indentation in the admin
queue command header file.

Neerav converts the use of udelay() to usleep_range().

Anjali fixes a bug where receive would stop after some stress by adding
a sleep and restart as well as moving the setting of flow control because
it should be done at a PF level and not a VSI level.

Mitch adds code to handle link events when updating the PF switch, which
allows link information to be properly provided to VFS in all cases.

Catherine adds driver support for 10GBaseT and bumps driver version.

Marvell PXA168 libphy handling and Berlin Ethernet

This patch series deals with a removing a IP feature that can be found
on all currently supported Marvell Ethernet IP (pxa168_eth, mv643xx_eth,
mvneta). The MAC IP allows to automatically perform PHY auto-negotiation
without software interaction.

However, this feature (a) fundamentally clashes with the way libphy works
and (b) is unable to deal with quirky PHYs that require special treatment.
In this series, pxa168_eth driver is rewritten to completely disable that
feature and properly deal with libphy provided PHYs.

As usual, a branch on top of v3.18-rc1 can be found at

git://git.infradead.org/users/hesselba/linux-berlin.git devel/bg2-bg2cd-eth-v2

Patches 1-5 should go through David's net tree, I'll pick up the DT patches
6-9.

There have been some changes,
compared to the RFT
- added phy-connection-type property to BG2Q PHY DT node
- bail out from pxa168_eth_adjust_link when there is no change in
  PHY parameters. Also, add a call to phy_print_status.
compared to v1
- move phy-connection-type to ethernet node instead of PHY node

Patch 1 adds support for Marvell 88E3016 FastEthernet PHY that is also
integrated in Marvell Berlin BG2/BG2CD SoCs.

Patch 2 allows to pass phy_interface_t on pxa168_eth platform_data that
is only used by mach-mmp/gplug. From the board setup, I guessed gplug's
PHY is connected via RMII. The patch still isn't even compile tested.

Patches 3-5 prepare proper libphy handling and finally remove all in-driver
PHY mangling related to the feature explained above.

Patches 6-9 add corresponding ethernet DT nodes to BG2, BG2CD, add a
phy-connection-type property to BG2Q and enable ethernet on BG2-based Sony
NSZ-GS7. I have tested all this on GS7 successfully with ip=dhcp on 100M FD.
