      net: Add full IPv6 addresses to flow_keys · c3f83241
      Tom Herbert 提交于
      This patch adds full IPv6 addresses into flow_keys and uses them as
      input to the flow hash function. The implementation supports either
      IPv4 or IPv6 addresses in a union, and selector is used to determine
      how may words to input to jhash2.
      
      We also add flow_get_u32_dst and flow_get_u32_src functions which are
      used to get a u32 representation of the source and destination
      addresses. For IPv6, ipv6_addr_hash is called. These functions retain
      getting the legacy values of src and dst in flow_keys.
      
      With this patch, Ethertype and IP protocol are now included in the
      flow hash input.

      etherdev: Fix sparse error, make test usable by other functions · 2c7a88c2
      Alexander Duyck 提交于
      This change does two things.  First it fixes a sparse error for the fact
      that the __be16 degrades to an integer.  Since that is actually what I am
      kind of doing I am simply working around that by forcing both sides of the
      comparison to u16.
      
      Also I realized on some compilers I was generating another instruction for
      big endian systems such as PowerPC since it was masking the value before
      doing the comparison.  So to resolve that I have simply pulled the mask out
      and wrapped it in an #ifndef __BIG_ENDIAN.
      
      Lastly I pulled this all out into its own function.  I notices there are
      similar checks in a number of other places so this function can be reused
      there to help reduce overhead in these paths as well.

      net: dsa: reduce number of protocol hooks · 3e8a72d1
      Florian Fainelli 提交于
      DSA is currently registering one packet_type function per EtherType it
      needs to intercept in the receive path of a DSA-enabled Ethernet device.
      Right now we have three of them: trailer, DSA and eDSA, and there might
      be more in the future, this will not scale to the addition of new
      protocols.
      
      This patch proceeds with adding a new layer of abstraction and two new
      functions:
      
      dsa_switch_rcv() which will dispatch into the tag-protocol specific
      receive function implemented by net/dsa/tag_*.c
      
      dsa_slave_xmit() which will dispatch into the tag-protocol specific
      transmit function implemented by net/dsa/tag_*.c
      
      When we do create the per-port slave network devices, we iterate over
      the switch protocol to assign the DSA-specific receive and transmit
      operations.
      
      A new fake ethertype value is used: ETH_P_XDSA to illustrate the fact
      that this is no longer going to look like ETH_P_DSA or ETH_P_TRAILER
      like it used to be.
      
      This allows us to greatly simplify the check in eth_type_trans() and
      always override the skb->protocol with ETH_P_XDSA for Ethernet switches
      tagged protocol, while also reducing the number repetitive slave
      netdevice_ops assignments.

      net: add ETH_P_802_3_MIN · e5c5d22e
      Simon Horman 提交于
      Add a new constant ETH_P_802_3_MIN, the minimum ethernet type for
      an 802.3 frame. Frames with a lower value in the ethernet type field
      are Ethernet II.
      
      Also update all the users of this value that David Miller and
      I could find to use the new constant.
      
      Also correct a bug in util.c. The comparison with ETH_P_802_3_MIN
      should be >= not >.
      
      As suggested by Jesse Gross.
      
      Compile tested only.

      net: add IFF_SKB_TX_SHARED flag to priv_flags · d8873315
      Neil Horman 提交于
      Pktgen attempts to transmit shared skbs to net devices, which can't be used by
      some drivers as they keep state information in skbs.  This patch adds a flag
      marking drivers as being able to handle shared skbs in their tx path.  Drivers
      are defaulted to being unable to do so, but calling ether_setup enables this
      flag, as 90% of the drivers calling ether_setup touch real hardware and can
      handle shared skbs.  A subsequent patch will audit drivers to ensure that the
      flag is set properly
