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.

When we scan a packet for GRO processing, we want to see the most common packet types in the front of the offload_base list. So add a priority field so we can handle this properly. IPv4/IPv6 get the highest priority with the implicit zero priority field. Next comes ethernet with a priority of 10, and then we have the MPLS types with a priority of 15.

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.

Avoid recomputing the Ethernet header location and instead just use the pointer provided by skb->data. The problem with using eth_hdr is that the compiler wasn't smart enough to realize that skb->head + skb->mac_header was the same thing as skb->data before it added ETH_HLEN. By just caching it off before calling skb_pull_inline we can avoid a few unnecessary instructions. Signed-off-by: NAlexander Duyck <alexander.h.duyck@redhat.com> Signed-off-by: NDavid S.

This change makes it so that we process the address in is_multicast_ether_addr at the same size as the other calls. This allows us to avoid duplicate reads when used with other calls such as is_zero_ether_addr or eth_addr_copy. In addition I have added a 64 bit version of the function so in eth_type_trans we can process the destination address as a 64 bit value throughout.

This change takes advantage of the fact that ETH_P_802_3_MIN is aligned to 512 so as a result we can actually ignore the lower 8b when comparing the Ethertype to ETH_P_802_3_MIN. This allows us to avoid a byte swap by simply masking the value and comparing it to the byte swapped value for ETH_P_802_3_MIN.

This patch updates some of the flow_dissector api so that it can be used to parse the length of ethernet buffers stored in fragments. Most of the changes needed were to __skb_get_poff as it needed to be updated to support sending a linear buffer instead of a skb. I have split __skb_get_poff into two functions, the first is skb_get_poff and it retains the functionality of the original __skb_get_poff. The other function is __skb_get_poff which now works much like __skb_flow_dissect in relation to skb_flow_dissect in that it provides the same functionality but works with just a data buffer and hlen instead of needing an skb.

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.

eth_type_trans() can read uninitialized memory as drivers do not necessarily pull more than 14 bytes in skb->head before calling it. As David suggested, we can use skb_header_pointer() to fix this without breaking some drivers that might not expect eth_type_trans() pulling 2 additional bytes.
