* etherdev: Fix sparse error, make test usable by other functionsAlexander Duyck2015-05-051-0/+18
| | | | | | | | | | | | | | | | | | | 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.

* etherdev: Process is_multicast_ether_addr at same size as other operationsAlexander Duyck2015-05-031-1/+23
| | | | | | | | | | | | 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.

* net: Add functions for handling padding frame and adding to lengthAlexander Duyck2014-12-081-0/+12
| | | | | | | | | | | | | | | | | | | | | | This patch adds two new helper functions skb_put_padto and eth_skb_pad. These functions deviate from the standard skb_pad or skb_padto in that they will also update the length and tail pointers so that they reflect the padding added to the frame. The eth_skb_pad helper is meant to be used with Ethernet devices to update either Rx or Tx frames so that they report the correct size. The skb_put_padto helper is meant to be used primarily in the transmit path for network devices that need frames to be padded up to some minimum size and don't wish to simply update the length somewhere external to the frame. The motivation behind this is that there are a number of implementations throughout the network device drivers that are all doing the same thing, but each a little bit differently and as a result several implementations contain bugs such as updating the length without updating the tail offset and other similar issues.

* net: Add function for parsing the header length out of linear ethernet framesAlexander Duyck2014-09-051-0/+1
| | | | | | | | | | | | | | | | | 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.

* net, ixgbe: handle link local multicast addresses in SR-IOV modeJohn Fastabend2012-10-291-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In SR-IOV mode the PF driver acts as the uplink port and is used to send control packets e.g. lldpad, stp, etc. eth0.1 eth0.2 eth0 VF VF PF | | | <-- stand-in for uplink | | | -------------------------- | Embedded Switch | -------------------------- | MAC <-- uplink But the embedded switch is setup to forward multicast addresses to all interfaces both VFs and PF and onto the physical link. This results in reserved MAC addresses used by control protocols to be forwarded over the switch onto the VF. In the LLDP case the PF sends an LLDPDU and it is currently being forwarded to all the VFs who then see the PF as a peer. This is incorrect. This patch adds the multicast addresses to the RAR table in the hardware to prevent this behavior.

| | | | | | | | | | | | | | | | | | | | | Add addr_assign_type to struct net_device and expose it via sysfs. This new attribute has the purpose of giving user-space the ability to distinguish between different assignment types of MAC addresses. For example user-space can treat NICs with randomly generated MAC addresses differently than NICs that have permanent (locally assigned) MAC addresses. For the former udev could write a persistent net rule by matching the device path instead of the MAC address. There's also the case of devices that 'steal' MAC addresses from slave devices. In which it is also be beneficial for user-space to be aware of the fact. This patch also introduces a helper function to assist adoption of drivers that generate MAC addresses randomly.
