      gianfar: Use mpc85xx support for errata detection · 2969b1f7
      由 Claudiu Manoil 提交于 
      Use the macros and defines from mpc85xx.h to simplify
and prevent errors in identifying a mpc85xx based SoC
for errata detection.
This should help enabling (and identifying) workarounds
for various mpc85xx based chips and revisions.
For instance, express MPC8548 Rev.2 as:
(SVR_SOC_VER(svr) == SVR_8548) && (SVR_REV(svr) == 0x20)
instead of:
(pvr == 0x80210020 && mod == 0x8030 && rev == 0x0020)

      gianfar: Enable eTSEC-A002 erratum w/a for all parts · ad3660c2
      由 Claudiu Manoil 提交于 
      A002 is still in "no plans to fix" state, and applies to all
the current P1/P2 parts as well, so it's resonable to enable
its workaround by default, for all the soc's with etsec.
The impact of not enabling this workaround for affected parts
is that under certain conditons (runt frames or even frames
with RX error detected at PHY level) during controller reset,
the controller might fail to indicate Rx reset (GRS) completion.

      Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec · f6063850
      由 David S. Miller 提交于 
      Steffen Klassert says:

====================
1) We used the wrong netlink attribute to verify the
   lenght of the replay window on async events. Fix this by
   using the right netlink attribute.

2) Policy lookups can not match the output interface on forwarding.
   Add the needed informations to the flow informations.

3) We update the pmtu when we receive a ICMPV6_DEST_UNREACH message
   on IPsec with ipv6. This is wrong and leads to strange fragmented
   packets, only ICMPV6_PKT_TOOBIG messages should update the pmtu.
   Fix this by removing the ICMPV6_DEST_UNREACH check from the IPsec
   protocol error handlers.

4) The legacy IPsec anti replay mechanism supports anti replay
   windows up to 32 packets. If a user requests for a bigger
   anti replay window, we use 32 packets but pretend that we use
   the requested window size. Fix from Fan Du.

5) If asynchronous events are enabled and replay_maxdiff is set to
   zero, we generate an async event for every received packet instead
   of checking whether a timeout occurred. Fix from Thomas Egerer.

6) Policies need a refcount when the state resolution timer is armed.
   Otherwise the timer can fire after the policy is deleted.

7) We might dreference a NULL pointer if the hold_queue is empty,
   add a check to avoid this.

      net: secure_seq: Fix warning when CONFIG_IPV6 and CONFIG_INET are not selected · cb03db9d
      由 Fabio Estevam 提交于 
      net_secret() is only used when CONFIG_IPV6 or CONFIG_INET are selected.

Building a defconfig with both of these symbols unselected (Using the ARM
at91sam9rl_defconfig, for example) leads to the following build warning:

$ make at91sam9rl_defconfig
#
# configuration written to .config
#

$ make net/core/secure_seq.o
scripts/kconfig/conf --silentoldconfig Kconfig
  CHK     include/config/kernel.release
  CHK     include/generated/uapi/linux/version.h
  CHK     include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
  CALL    scripts/checksyscalls.sh
  CC      net/core/secure_seq.o
net/core/secure_seq.c:17:13: warning: 'net_secret_init' defined but not used [-Wunused-function]

Fix this warning by protecting the definition of net_secret() with these
symbols.

      sfc: Add PM and RXDP drop counters to ethtool stats · 568d7a00
      由 Edward Cree 提交于 
      Recognise the new Packet Memory and RX Data Path counters.

The following counters are added:
rx_pm_{trunc,discard}_bb_overflow - burst buffer overflowed.  This should not
 occur if BB correctly configured.
rx_pm_{trunc,discard}_vfifo_full - not enough space in packet memory.  May
 indicate RX performance problems.
rx_pm_{trunc,discard}_qbb - dropped by 802.1Qbb early discard mechanism.
 Since Qbb is not supported at present, this should not occur.
rx_pm_discard_mapping - 802.1p priority configured to be dropped.  This should
 not occur in normal operation.
rx_dp_q_disabled_packets - packet was to be delivered to a queue but queue is
 disabled.  May indicate misconfiguration by the driver.
rx_dp_di_dropped_packets - parser-dispatcher indicated that a packet should be
 dropped.
rx_dp_streaming_packets - packet was sent to the RXDP streaming bus, ie. a
 filter directed the packet to the MCPU.
rx_dp_emerg_{fetch,wait} - RX datapath had to wait for descriptors to be
 loaded.  Indicates performance problems but not drops.

These are only provided if the MC firmware has the
PM_AND_RXDP_COUNTERS capability.  Otherwise, mask them out.

      sfc: Refactor EF10 stat mask code to allow for more conditional stats · 4bae913b
      由 Edward Cree 提交于 
      Previously, efx_ef10_stat_mask returned a static const unsigned long[], which
meant that each possible mask had to be declared statically with
STAT_MASK_BITMAP.  Since adding a condition would double the size of the
decision tree, we now create the bitmask dynamically.

To do this, we have two functions efx_ef10_raw_stat_mask, which returns a u64,
and efx_ef10_get_stat_mask, which fills in an unsigned long * argument.
