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:

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. With this change we see the 64-byte packets per second numbers improve by about 4%. Signed-off-by:

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: -

We want to try and pull the L4 header in if it is available in the first fragment. As such add the flag to indicate we want to pull the headers on the first fragment in. Signed-off-by:

The IPv6 parsing was using a local pointer when it could use the same pointer as the IPv4 portion of the code since the key_addrs can support both IPv4 and IPv6 as it is just a pointer. Signed-off-by:

The flow dissector bits handling FCoE didn't bother to actually validate that the space there was enough for the FCoE header. So we need to update things so that if there is room we add the header and report a good result, otherwise we do not add the header, and report the bad result. Signed-off-by:

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. Signed-off-by:

Alexander Duyck authored
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. Fixes: 807e165d ("flow_dissector: Add control/reporting of fragmentation") Signed-off-by:

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. The series where applied on top of: ("5270c4da Merge branch 'vxlan-cleanups'") + latest mlx5 ifc and ndo fixes from net tree. ==================== Signed-off-by: -

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. CC: John Fastabend <john.fastabend@gmail.com> Signed-off-by:

One of the validation checks for the new array-based TCP SO_REUSEPORT validation was unintentionally dropped in ea8add2b. This adds it back. Lack of this check allows the user to allocate multiple sock_reuseport structures (leaking all but the first). Fixes: ea8add2b ("tcp/dccp: better use of ephemeral ports in bind()") Signed-off-by:

Vivien Didelot says: ==================== net: dsa: pass bridge device to drivers This patchset simplifies the DSA layer. A switch may support multiple bridges with the same hardware VLAN. Thus a check such as dsa_bridge_check_vlan_range must be moved from the DSA layer to the concerned driver. The first purpose of this patchset is to help moving this check to the mv88e6xxx driver, which is the only one affected at the moment. To do that, pass directly the bridge net_device structure down to the DSA drivers, instead of calculating a bitmask of bridge members. The second purpose is to prepare the replacement of the complex port_vlan_getnext approach. A second patchset is ready to follow, implementing port_vlan_dump and thus simplifying the DSA slave code one more time. Note that this patchset applies on top of https://lkml.org/lkml/2016/2/5/532. ==================== Signed-off-by:

DSA drivers may support multiple bridge groups with the same hardware VLAN. The mv88e6xxx driver which cannot yet, already has its own check for overlapping bridges. Thus remove the check from the DSA layer. Signed-off-by:

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:

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.
