2016-02-26phy: marvell: Fix 88E1510 initializationClemens Gruber1-35/+35
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.

2016-02-25bnx2x: add a separate GENEVE Kconfig symbolArnd Bergmann2-7/+17

2016-02-25igb: call ndo_stop() instead of dev_close() when running offline selftestStefan Assmann3-6/+8
Calling dev_close() causes IFF_UP to be cleared which will remove the interfaces routes and some addresses. That's probably not what the user intended when running the offline selftest. Besides this does not happen if the interface is brought down before the test, so the current behaviour is inconsistent. Instead call the net_device_ops ndo_stop function directly and avoid touching IFF_UP at all.

2016-02-25igb: Fix VLAN tag stripping on Intel i350Corinna Vinschen1-9/+32
Problem: When switching off VLAN offloading on an i350, the VLAN interface gets unusable. For testing, set up a VLAN on an i350 and some remote machine, e.g.: $ ip link add link eth0 name eth0.42 type vlan id 42 $ ip addr add 192.168.42.1/24 dev eth0.42 $ ip link set dev eth0.42 up Offloading is switched on by default: $ ethtool -k eth0 | grep vlan-offload rx-vlan-offload: on tx-vlan-offload: on $ ping -c 3 -I eth0.42 192.168.42.2 [...works as usual...] Now switch off VLAN offloading and try again: $ ethtool -K eth0 rxvlan off Actual changes: rx-vlan-offload: off tx-vlan-offload: off [requested on] $ ping -c 3 -I eth0.42 192.168.42.2 PING 192.168.42.2 (192.168.42.2) from 192.168.42.1 eth0.42: 56(84) bytes of da ta. --- 192.168.42.2 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 1999ms I can only reproduce it on an i350, the above works fine on a 82580. While inspecting the igb source, I came across the code in igb_set_vmolr which sets the E1000_VMOLR_STRVLAN/E1000_DVMOLR_STRVLAN flags once and for all, and in all of the igb code there's no other place where the STRVLAN is set or cleared. Thus, VLAN stripping is enabled in igb unconditionally, independently of the offloading setting. I compared that to the latest Intel igb-5.3.3.5 driver from http://sourceforge.net/projects/e1000/ which in fact sets and clears the STRVLAN flag independently from igb_set_vmolr in its own function igb_set_vf_vlan_strip, depending on the vlan settings. So I included the STRVLAN handling from the igb-5.3.3.5 driver into our current igb driver and tested the above scenario again. This time ping still works after switching off VLAN offloading. Tested on i350, with and without addtional VFs, as well as on 82580 successfully.

2016-02-25igbvf: remove "link is Up" message when registering mcast addressJon Maxwell1-1/+0
A similar issue was addressed a few years ago in the following thread: http://www.spinics.net/lists/netdev/msg245877.html At that time there were concerns that removing this statement may cause other side effects. However the submitter addressed those concerns. But the dialogue went cold. We have a new case where a customers application is registering and un-registering multicast addresses every few seconds. This is leading to many "Link is Up" messages in the logs as a result of the "netif_carrier_off(netdev)" statement called by igbvf_msix_other(). Also on some kernels it is interfering with the bonding driver causing it to failover and subsequently affecting connectivity. The Sourgeforge driver does not make this call and is therefore not affected. If there were any side effects I would expect that driver to also be affected. I have tested re-loading the igbvf driver and downing the adapter with the PF entity on the host where the VM has this patch. When I bring it back up again connectivity is restored as expected. Therefore I request that this patch gets submitted.

2016-02-25igbvf: Add support for generic Tx checksumsAlexander Duyck2-61/+82
This patch adds support for generic Tx checksums to the igbvf driver. It turns out this is actually pretty easy after going over the datasheet as we were doing a number of steps we didn't need to. In order to perform a Tx checksum for an L4 header we need to fill in the following fields in the Tx descriptor: MACLEN (maximum of 127), retrieved from: skb_network_offset() IPLEN (maximum of 511), retrieved from: skb_checksum_start_offset() - skb_network_offset() TUCMD.L4T indicates offset and if checksum or crc32c, based on: skb->csum_offset The added advantage to doing this is that we can support inner checksum offloads for tunnels and MPLS while still being able to transparently insert VLAN tags. I also took the opportunity to clean-up many of the feature flag configuration bits to make them a bit more consistent between drivers. In the case of the VF drivers this meant adding support for SCTP CRCs, and inner checksum offloads for MPLS and various tunnel types.

2016-02-25igb: add conditions for I210 to generate periodic clock outputRoland Hii1-1/+2
In general case the maximum supported half cycle time of the synchronized output clock is 70msec. Slower half cycle time than 70msec can be programmed also as long as the output clock is synchronized to whole seconds, useful specifically for generating a 1Hz clock. Permitted values for the clock half cycle time are: 125,000,000 decimal, 250,000,000 decimal and 500,000,000 decimal (equals to 125msec, 250msec and 500msec respectively). Before this patch, only the half cycle time of less than or equal to 70msec uses the I210 clock output function. This patch adds additional conditions when half cycle time is equal to 125msec or 250msec or 500msec to use clock output function. Under other conditions, interrupt driven target time output events method is still used to generate the desired clock output.

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.

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.

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.

2016-02-24net/mlx5: Introduce a new header file for physical port functionsAchiad Shochat2-0/+2
All the device physical port access functions are implemented in the port.c file. We just extract the exposure of these functions from driver.h into a dedicated header file called port.h.

2016-02-23net: dsa: mv88e6xxx: check hardware VLAN in useVivien Didelot1-0/+64
The DSA drivers now have access to the VLAN prepare phase and the bridge net_device. It is easier to check for overlapping bridges from within the driver. Thus add such check in mv88e6xxx_port_vlan_prepare. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-02-23net: dsa: pass bridge down to driversVivien Didelot4-9/+24
Some DSA drivers may or may not support multiple software bridges on top of an hardware switch. It is more convenient for them to access the bridge's net_device for finer configuration. Removing the need to craft and access a bitmask also simplifies the code. This patch changes the signature of bridge related functions, update DSA drivers, and removes dsa_slave_br_port_mask.
