      netlink: Remove netlink_compare_arg.trailer · 8f2ddaac
      由 Herbert Xu 提交于 
      Instead of computing the offset from trailer, this patch computes
netlink_compare_arg_len from the offset of portid and then adds 4
to it.  This allows trailer to be removed.

====================
NetCP: Add support for version 1.5

NetCP 1.5 is used in newer K2 SoCs from Texas Instruments
such as K2E, K2L etc. This patch series add support for Ethss
driver for this version of NetCP. While at it, fix couple of
bugs in the original driver.

One of the earlier patch "net: netcp: select davinci_mdio driver
by default" is folded onto this series.

Please review and let me know your comments.

      net: netcp: ethss: enhancement to support NetCP 1.5 ethss · 9a391c7b
      由 WingMan Kwok 提交于 
      NetCP 1.5 available on newer K2 SoCs such as K2E and K2L introduced 3
variants of the ethss subsystem, 9 port, 5 port and 2 port. These have
one host port towards the CPU and N external slave ports.

To customize the driver for these new ethss sub systems, multiple
compatibility strings are introduced. Currently some of parameters that
are different on different variants such as number of ALE ports, stats
modules and number of ports are defined through constants. These are now
changed to variables in gbe_priv data that get set based on the
compatibility string. This is required as there are no hardware
identification registers available to distinguish among the variants
of NetCP 1.5 ethss. However there is identification register available
to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use
of in the code to differentiate them.

      net: netcp: use separate reg region for individual ethss modules · 21e0e0dd
      由 Karicheri, Muralidharan 提交于 
      Ethss has multiple modules within the sub system
 - switch sub system
 - sgmii
 - mdio
 - switch module

NetCP driver re-uses existing davinci mdio driver. It requires to
have its own register region to map the reg space. So restructure
the code to use separate reg region for the individual modules it
manages. Use range property to define register space of NetCP and
use reg property to define individual reg spaces. So MDIO will have
its own reg space to map. This is a pre-requisite to enable MDIO
driver for NetCP.

      net: netcp: fix forward port number usage for 10G ethss · e170f409
      由 Karicheri, Muralidharan 提交于 
      10G switch requires forward port number in the taginfo field,
where as it should be in packet_info field for necp 1.4 Ethss. So
fill this value correctly in the knav dma descriptor.

Also rename dma_psflags field in struct netcp_tx_pipe to switch_to_port
as it contain no flag, but the switch port number for forwarding the
packet. Add a flag to hold the new flag,  SWITCH_TO_PORT_IN_TAGINFO which
will be set for 10G. This can also used in the future for other flags for
the tx_pipe.

      由 YOSHIFUJI Hideaki/吉藤英明 提交于 
      net: neighbour: Add mcast_resolicit to configure the number of multicast resolicitations in PROBE state.

We send unicast neighbor (ARP or NDP) solicitations ucast_probes
times in PROBE state.  Zhu Yanjun reported that some implementation
does not reply against them and the entry will become FAILED, which
is undesirable.

We had been dealt with such nodes by sending multicast probes mcast_
solicit times after unicast probes in PROBE state.  In 2003, I made
a change not to send them to improve compatibility with IPv6 NDP.

Let's introduce per-protocol per-interface sysctl knob "mcast_
reprobe" to configure the number of multicast (re)solicitation for
reconfirmation in PROBE state.  The default is 0, since we have
been doing so for 10+ years.

Intel Wired LAN Driver Updates 2015-03-20

This series contains updates to ixgb, e1000e, igb and igbvf.

Eliezer and Todd provide patches to fix a potential issue found during code
inspection.  When bringing down an interface netif_carrier_off() should
be one of the first things we do, since this will prevent the stack from
queueing more packets to this interface.

Yanir provides a fix for e1000e that was found in validating i219,
where the call to e1000e_write_protect_nvm_ich8lan() is no longer
supported in newer hardware.  Access to these registers causes a
system freeze in early steppings and is ignored in later steppings.
