      net: macb: Add hardware PTP support · ab91f0a9
      Rafal Ozieblo authored
      This patch is based on original Harini's patch and Andrei's patch,
      implemented in a separate file to ease the review/maintanance
      and integration with other platforms.
      
      This driver supports GEM-GXL:
      - Register ptp clock framework
      - Initialize PTP related registers
      - HW time stamp on the PTP Ethernet packets are received using the
        SO_TIMESTAMPING API. Time stamps are obtained from the dma buffer
        descriptors
      - add macb_ptp to compilation chain

      Rafal Ozieblo authored
      In case that macb is compiled as a module, macb.c has been renamed to
      macb_main.c to avoid naming confusion in Makefile.

      ====================
      Netfilter updates for net-next
      
      The following patchset contains Netfilter updates for your net-next
      tree. This batch contains connection tracking updates for the cleanup
      iteration path, patches from Florian Westphal:
      
      X) Skip unconfirmed conntracks in nf_ct_iterate_cleanup_net(), just set
         dying bit to let the CPU release them.
      
      X) Add nf_ct_iterate_destroy() to be used on module removal, to kill
         conntrack from all namespace.
      
      X) Restart iteration on hashtable resizing, since both may occur at
         the same time.
      
      X) Use the new nf_ct_iterate_destroy() to remove conntrack with NAT
         mapping on module removal.
      
      X) Use nf_ct_iterate_destroy() to remove conntrack entries helper
         module removal, from Liping Zhang.
      
      X) Use nf_ct_iterate_cleanup_net() to remove the timeout extension
         if user requests this, also from Liping.
      
      X) Add net_ns_barrier() and use it from FTP helper, so make sure
         no concurrent namespace removal happens at the same time while
         the helper module is being removed.
      
      X) Use NFPROTO_MAX in layer 3 conntrack protocol array, to reduce
         module size. Same thing in nf_tables.
      
      Updates for the nf_tables infrastructure:
      
      X) Prepare usage of the extended ACK reporting infrastructure for
         nf_tables.
      
      X) Remove unnecessary forward declaration in nf_tables hash set.
      
      X) Skip set size estimation if number of element is not specified.
      
      X) Changes to accomodate a (faster) unresizable hash set implementation,
         for anonymous sets and dynamic size fixed sets with no timeouts.
      
      X) Faster lookup function for unresizable hash table for 2 and 4
         bytes key.
      
      And, finally, a bunch of asorted small updates and cleanups:
      
      X) Do not hold reference to netdev from ipt_CLUSTER, instead subscribe
         to device events and look up for index from the packet path, this
         is fixing an issue that is present since the very beginning, patch
         from Xin Long.
      
      X) Use nf_register_net_hook() in ipt_CLUSTER, from Florian Westphal.
      
      X) Use ebt_invalid_target() whenever possible in the ebtables tree,
         from Gao Feng.
      
      X) Calm down compilation warning in nf_dup infrastructure, patch from
         stephen hemminger.
      
      X) Statify functions in nftables rt expression, also from stephen.
      
      X) Update Makefile to use canonical method to specify nf_tables-objs.
         From Jike Song.
      
      X) Use nf_conntrack_helpers_register() in amanda and H323.
      
      X) Space cleanup for ctnetlink, from linzhang.

        The other is a fix for a leak of the bio protection info, if smaller

      sfc: fix attempt to translate invalid filter ID · d58299a4
      Edward Cree authored
      When filter insertion fails with no rollback, we were trying to convert
       EFX_EF10_FILTER_ID_INVALID to an id to store in 'ids' (which is either
       vlan->uc or vlan->mc).  This would WARN_ON_ONCE and then record a bogus
       filter ID of 0x1fff, neither of which is a good thing.

      net/mlx4_en: Do not allocate redundant TX queues when TC is disabled · ec327f7a
      Inbar Karmy authored
      Currently the number of TX queues that are allocated doesn't depend
      on the number of TCs, the module always loads with max num of UP
      per channel.
      In order to prevent the allocation of unnecessary memory, the
      module will load with minimum number of UPs per channel, and the
      user will be able to control the number of TX queues per channel
      by changing the number of TC to 8 using the tc command.
      The variable num_up will hold the information about the current
      number of UPs.
      Due to the change, needed to remove the lines that set the value of
      UP to be different than zero in the func "mlx4_en_select_queue",
      since now the num of TX queues that are allocated is only one per channel
      in default.
      In order not to force the UP to be zero in case of only one TC, added
      a condition before forcing it in the func "mlx4_en_fill_qp_context".
      
      Tested:
      After the module is loaded with minimum number of UP per channel, to
      increase num of TCs to 8, use:
      tc qdisc add dev ens8 root mqprio num_tc 8
      In order to decrease the number of TCs to minimum number of UP per channel,
      use:
      tc qdisc del dev ens8 root
