Intel Wired LAN Driver Updates 2015-03-09

This series contains updates to i40e and i40evf.

Greg cleans up some "hello world" strings which were left around from
early development.

Shannon modifies the drive to make sure the sizeof() calls are taking
the size of the actual struct that we care about.  Also updates the
NVMUpdate read/write so that it is less noisy when logging.  This was
because the NVMUpdate tool does not necessarily know the ReadOnly map of
the current NVM image, and must try reading and writing words that may be
protected.  This generates an error out of the Firmware request that the
driver logs.  Unfortunately, this ended up spitting out hundreds of
bogus read/write error messages.  If a user wants the noisy logging,
the change can be overridden by enabling the NVM update debugging.

Mitch fixes a possible deadlock issue where if a reset occurred when the
netdev is closed, the reset task will hang in napi_disable.  Added
ethtool RSS support as suggested by Ben Hutchings.

Jesse fixes a bug introduced in the force writeback code, where the
interrupt rate was set to 0 (maximum) by accident.  The driver must
correctly set the NOITR fields to avoid IT update as a side effect
of triggering the software interrupt.

I provided a simple cleanup to make the use of PF/VF consistent, which
was reported by Joe Perches.

Netfilter updates for net-next

The following patchset contains Netfilter updates for your net-next
tree. Basically, improvements for the packet rejection infrastructure,
deprecation of CLUSTERIP, cleanups for nf_tables and some untangling for
br_netfilter. More specifically they are:

1) Send packet to reset flow if checksum is valid, from Florian Westphal.

2) Fix nf_tables reject bridge from the input chain, also from Florian.

3) Deprecate the CLUSTERIP target, the cluster match supersedes it in
   functionality and it's known to have problems.

4) A couple of cleanups for nf_tables rule tracing infrastructure, from
   Patrick McHardy.

5) Another cleanup to place transaction declarations at the bottom of
   nf_tables.h, also from Patrick.

6) Consolidate Kconfig dependencies wrt. NF_TABLES.

7) Limit table names to 32 bytes in nf_tables.

8) mac header copying in bridge netfilter is already required when
   calling ip_fragment(), from Florian Westphal.

9) move nf_bridge_update_protocol() to br_netfilter.c, also from
   Florian.

10) Small refactor in br_netfilter in the transmission path, again from
    Florian.

11) Move br_nf_pre_routing_finish_bridge_slow() to br_netfilter.

Commit 9bbb4ecc ("tipc: standardize recvmsg routine") changed
the sleep/wakeup behaviour for sockets entering recv() or accept().
In this process the order of reporting -EAGAIN/-EINTR was reversed.
This caused problems with wrong errno being reported back if the
timeout expires. The same problem happens if the socket is
nonblocking and recv()/accept() is called when the process have
pending signals. If there is no pending data read or connections to
accept, -EINTR will be returned instead of -EAGAIN.

Kernel automatically creates a tp for each
(kind, protocol, priority) tuple, which has handle 0,
when we add a new filter, but it still is left there
after we remove our own, unless we don't specify the
handle (literally means all the filters under
the tuple). For example this one is left:

  # tc filter show dev eth0
  filter parent 8001: protocol arp pref 49152 basic

The user-space is hard to clean up these for kernel
because filters like u32 are organized in a complex way.
So kernel is responsible to remove it after all filters
are gone.  Each type of filter has its own way to
store the filters, so each type has to provide its
way to check if all filters are gone.

Unfortunately, this ends up spitting out hundreds of bogus read and write

This patch checks the error type and under normal conditions will not print
the typical read and write errors during NVMUpdate.  This can be overridden
by enabling the NVM update debugging.  This results in a much less messy log

Intel Wired LAN Driver Updates 2015-03-07

This series contains updates to i40e and i40evf only.

Most notably, Greg provides the patch to remove the dreaded configfs
changes in the driver.

Shannon cleans up a sparse warning by simply straighting out the code
so it is less convoluted.  Fixes an issue where the vector allocation
was trying too hard to save vectors for VMDq, to the point of not giving
the PF enough when in a tight situation, such as an NPAR partition.
Changed the driver to make sure that the PF will get all the queues and
vectors it wants to fill out its destiny.  Cleans up reporting to only
print the port and VEB stats if it is the first partition of a
multiplexed port.

Catherine cleans up some duplicated code by simply removing the duplicate
code.

Kamil cleans up the driver by removing an un-needed endian conversion
because it is already done by a register read function.

Jesse fixes a variable width of a datatype, where a u16 should have been
a u32.  Also cleans up debug_read_register() to resolve some sparse
warnings.  Updates the driver to use prefetch() to get the next Tx
descriptor, like in ixgbe, to improve performance.

Akeem moves around code to enable/disable loopback so that other non-SRIOV
supported driver functions can take advantage of the changes.

Anjali cleans up the logging for adding/deleting FD-SB filters, since
ethtool shows all the filters on an interface.  Updates the driver to
use l4_tunnel type generically to keep code flow simple.  Simplifies
the RSS code since the driver initializes the rss_size_max in sw_init.

net/macb: merge at91_ether driver into macb driver

The rm9200 boards use the dedicated at91_ether driver instead of the
regular macb driver.

Both the macb and at91_ether drivers can be compiled as separated
modules.
Since the at91_ether driver uses code from the macb driver, at91_ether.ko
depends on macb.ko.

However the macb.ko module always fails to load on rm9200 boards: the
macb_probe() function expects a hclk clock which doesn't exist on rm9200.
Then the at91_ether.ko can't be loaded in turn due to unresolved
dependencies.

This series of patches fix this issue by merging at91_ether into macb.

Patch 1 is fixing a problem that might happen when enabling ARM
multi-platform suppot.

Changes since v3:
- move "net: macb: remove #if defined(CONFIG_ARCH_AT91) sections" patch
  into this series to avoid dependency on other patch series.

Changes since v2:
- rebase after changed brought by commit "net: macb: remove #if
  defined(CONFIG_ARCH_AT91) sections"

Changes since v1:
- rework probe functions to share common probing logic
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

macb and at91_ether drivers can be compiled as modules, but the at91_ether
driver use some functions and variables defined in the macb one, thus
creating a dependency on the macb driver.

Since these drivers are sharing the same logic we can easily merge
at91_ether into macb.

In order to factorize common probing logic we've added an ->init() function
to struct macb_config (the structure associated with the compatible
string), and moved macb specific init code from macb_probe to macb_init.
