2016-02-25phy: marvell: Fix 88E1510 initializationClemens Gruber
A bug was introduced in the merge commit b633353115e3 ("Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net") The generic marvell_config_init (and therefore marvell_of_reg_init) is not called anymore for the Marvell 88E1510 (in net-next). This patch calls marvell_config_init and moves the specific init function for the 88E1510 below the marvell_config_init function to avoid adding a function predeclaration.

Jiri Benc says: ==================== vxlan: consolidate rx handling Currently, vxlan_rcv is just called at the end of vxlan_udp_encap_recv, continuing the rx processing where vxlan_udp_encap_recv left it. There's no clear border between those two functions. This patchset moves vxlan_udp_encap_recv and vxlan_rcv into a single function. This also allows to do some simplification in error path.

2016-02-25net_sched: add network namespace support for tc actionsWANG Cong
Currently tc actions are stored in a per-module hashtable, therefore are visible to all network namespaces. This is probably the last part of the tc subsystem which is not aware of netns now. This patch makes them per-netns, several tc action API's need to be adjusted for this. The tc action API code is ugly due to historical reasons, we need to refactor that code in the future.

We only release the memory of the hashtable itself, not its entries inside. This is not a problem yet since we only call it in module release path, and module is refcount'ed by actions.

* Split big conditional statement. * Check (data.length <= CCP_MAX_OPTION_LENGTH) only once. * Don't read ccp_option[1] if not initialised. Reading uninitialised ccp_option[1] was harmless, because this could only happen when data.length was 0 or 1.

2016-02-24bnx2x: add a separate GENEVE Kconfig symbolArnd Bergmann
When CONFIG_GENEVE is built as a loadable module, and bnx2x is built-in, we get this link error: drivers/net/built-in.o: In function `bnx2x_open': :(.text+0x33322): undefined reference to `geneve_get_rx_port' drivers/net/built-in.o: In function `bnx2x_sp_rtnl_task': :(.text+0x3e632): undefined reference to `geneve_get_rx_port' This avoids the problem by adding a separate Kconfig symbol named CONFIG_BNX2X_GENEVE that is only enabled when the code is reachable from the driver.

2016-02-24gianfar: Map head TxBD firstClaudiu Manoil
Move the mapping of the head BD before the mapping of fragments. The TOE (h/w offload) decision logic block can be also moved up (as the TOE flag belongs to the head BD), resulting in more localized code (TOE logic vs BD mapping code blocks). Note that, for this h/w, the R (status) bit for the head BD of a S/G frame needs to be written last for a reliable transmission. For the fragmented skb case, a local variable is used to temporarily store the status info of the first BD, replacing a BD status read. A merge of 2 "if(do_tstamp)" blocks was also possible.

2016-02-24be2net: Fix a UE caused by passing large frames to the ASICajit.khaparde@broadcom.com
In QnQ configurations like Flex-10 where the VLANs are inserted by the ASIC, on rare occasions the HW is encountering a scenario where the final frame length ends to be greater than what the ASIC can support. This is because when the TXULP pulls the TX WRB to check the length of the frame to be transmitted it also adds the size of VLANs to be inserted by the HW to the length of the frame indicated in the WRB, which in some cases fails the range check. This causes a UE. Avoid this by trimming the skb length to accommodate the VLAN insertion. Signed-off-by: Ajit Khaparde <ajit.khaparde@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-02-24be2net: Declare some u16 fields as u32 to improve performanceajit.khaparde@broadcom.com
When 16-bit integers are loaded on CPUs with high order native register sizes, the CPU could use some extra ops before using them. And currently some of the frequently used fields in the driver like the producer and consumer indices of the queues are declared as u16. This patch declares such fields as u32.

Alexander Duyck says: ==================== Flow dissector fixes and improvements This patch series is meant to fix and/or improve a number of items within the flow dissector code. The main change out of all of this is that IPv4 and IPv6 fragmentation should now be handled better than it was. As a result we should see an improvement when handling things like IP fragment reassembly as the skbs should now only have header data in the linear portion of the buffer while the fragments will only hold payload data. ==================== Signed-off-by: David S.

2016-02-24flow_dissector: Use same pointer for IPv4 and IPv6 addressesAlexander Duyck

2016-02-24flow_dissector: Correctly handle parsing FCoEAlexander Duyck
The flow dissector bits handling FCoE didn't bother to actually validate that the space there was enough for the FCoE header.

2016-02-24flow_dissector: Fix fragment handling for header length computationAlexander Duyck
It turns out that for IPv4 we were reporting the ip_proto of the fragment, and for IPv6 we were not. This patch updates that behavior so that we always report the IP protocol of the fragment. In addition it takes the steps of updating the payload offset code so that we will determine the start of the payload not including the L4 header for any fragment after the first.

2016-02-24flow_dissector: Check for IP fragmentation even if not using IPv4 addressAlexander Duyck
This patch corrects the logic for the IPv4 parsing so that it is consistent with how we handle IPv6. Specifically if we do not have the flow key indicating we want the addresses we still may need to take a look at the IP fragmentation bits and to see if we should stop after we have recognized the L3 header.

Saeed Mahameed says: ==================== QoS and VxLAN offloads support for Mellanox 100G mlx5 driver This patch series introduces QoS IEEE dcbnl support for PFC, ETS and max rate. In addition we added VxLAN support and introduced a patch that modifies the driver to report checksum complete in RX path for all IP (tunneled and non-tunneled) traffic which is non HW LRO. This series is applied on top of the latest mlx5_ifc and NDO fixes we sent to the net tree: net/mlx5e: Use static constant netdevice ndos net/mlx5e: Remove select queue ndo initialization net/mlx5: Use offset based reserved field names in the IFC header file The QoS patches depend on the IFC change since they expose new fields in the driver/firmware API. Both QoS and VxLAN patches depend on the NDO changes, since they add new ndo entries. Changes from V1: - Fixed the S.O.B from "Matt" to "Matthew" to be aligned with the committer title. - Don't populate VxLAN/dcbnl ndos for virtual functions. - Addressed John comment on mlx5_setup_tc to be aligned with latest API changes. - Added device ETS capability check prior query/modify ets configuration. - Call mlx5e_dcbnl_ieee_setets_core at the end of mlx5e_create_netdev and don't fail netdev creation in case it failed or ETS was not supported.

Support the ndo_setup_tc callback and the needed methods for multi TC/UP support, and removed the default_vlan_prio from mlx5e_priv which is always 0, it was replaced with hardcoded "0" in the new select queue method. For that we now create MAX_NUM_TC num of TISs (one per prio) on netdevice creation instead of priv->params.num_tc which was always 1. So far each channel had a single TXQ, Now each channel has a TXQ per TC (Traffic Class). Added en_dcbnl.c which implements the set/get DCBNL IEEE ETS, set/get dcbx and registers the mlx5e dcbnl ops. We still use the kernel's default TXQ selection method to select the channel to transmit through but now we use our own method to select the TXQ inside the channel based on VLAN priority. In mlx5, as opposed to mlx4, tc group N gets lower priority than tc group N+1.
