gre_multipath test was using egress vlan_id matching on flows, for the purpose of collecting next-hops statistics, later to be compared against configured weights. As matching on vlan_id on egress direction is not supported on all HW devices, change the match criteria to use destination IP. Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2018-08-07 This series contains updates to i40e and i40evf only. Sergey cleans up a duplicate call to i40e_prep_for_reset() during shutdown. YueHaibing cleans up i40evf by removing code that was never being used or called within the driver. Jake updates the ethtool statistics to use a helper function since many of the statistics use the same basic logic for copying strings into the supplied buffer. Cleaned up the use of a local variable that is no longer needed or used. Fixed additional stats issues, including the failure to update the data pointer which was causing stats to be reported incorrectly. Mariusz fixes a bug where there was an oversight in configuring FEC when link settings were forced which was causing 25G link to be configured incorrectly. Piotr adds a missing return code for when the firmware returns a busy state. Also added the process to command firmware to start rearrangement when switching between old NVM structure to the new flat NVM. ==================== Signed-off-by: -

Denis Bolotin says: ==================== qed: Add Multi-TC RoCE support This patch series adds support for multiple concurrent traffic classes for RoCE. The first three patches enable the required parts of the driver to learn the TC configuration, and the last one makes use of it to enable the feature. Please consider applying this to net-next. V1->V2: ------- Avoid allocation in qed_dcbx_get_priority_tc(). Move qed_dcbx_get_priority_tc() out of CONFIG_DCB section since it doesn't call qed_dcbx_query_params() anymore. v2->V3: ------- patch 1/3: qed_dcbx_get_priority_tc() always returns a valid TC by value. In error cases, it returns QED_DCBX_DEFAULT_TC (currently defined 0). patch 3/3: Cosmetic changes in qed_dev.c. ==================== Signed-off-by: -

RoCE qps use a pair of physical queues (pq) received from the Queue Manager (QM) - an offload queue (OFLD) and a low latency queue (LLT). The QM block creates a pq for each TC, and allows RoCE qps to ask for a pq with a specific TC. As a result, qps with different VLAN priorities can be mapped to different TCs, and employ features such as PFC and ETS. Signed-off-by:

Claudiu Beznea says: ==================== net: macb: add pad and fcs support In [1] it was reported that UDP checksum is offloaded to hardware no mather it was previously computed in software or not. The proposal on [1] was to disable TX checksum offload. This series (mostly patch 3/3) address the issue described at [1] by setting NOCRC bit to TX buffer descriptor for SKBs that arrived from networking stack with checksum computed. For these packets padding and FCS need to be added (hardware doesn't compute them if NOCRC bit is set). The minimum packet size that hardware expects is 64 bytes (including FCS). This feature could not be used in case of GSO, so, it was used only for no GSO SKBs. For SKBs wich requires padding and FCS computation macb_pad_and_fcs() checks if there is enough headroom and tailroom in SKB to avoid copying SKB structure. Since macb_pad_and_fcs() may change SKB the macb_pad_and_fcs() was places in macb_start_xmit() b/w macb_csum_clear() and skb_headlen() calls. This patch was tested with pktgen in kernel tool in a script like this: (pktgen_sample01_simple.sh is at [2]): minSize=1 maxSize=1500 for i in `seq $minSize $maxSize` ; do copy="$(shuf -i 1-2000 -n 1)" ./pktgen_sample01_simple.sh -i eth0 \ -m <dst-mac-addr> -d <dst-ip-addr> -x -s $i -c $copy done minStep=1 maxStep=200 for i in `seq $minStep $maxStep` ; do copy="$(shuf -i 1-2000 -n 1)" size="$(shuf -i 1-1500 -n 1)" ./pktgen_sample01_simple.sh -i eth0 \ -m <dst-mac-addr> -d <dst-ip-addr> -x -s $size -c $copy done Changes since RFC: - in patch 3/3 order local variables by their lenght (reverse christmas tree format) [1] https://www.spinics.net/lists/netdev/msg505065.html [2] https://github.com/netoptimizer/network-testing/blob/master/pktgen/pktgen_sample01_simple.sh ==================== Signed-off-by:

When backing device firmware reports an error, it provides an error ID, which is meant to be queried for more detailed error information. Currently, however, an error ID is not provided by the Virtual I/O server and there are not any plans to do so. For now, it is always unfilled or zero, so request_error_information will never be called. Remove it. Signed-off-by:

All control commands (soft commands) goes through only Queue 0 (control and data queue). So only queue-0 needs post_lock, other queues are only data queues and does not need post_lock Added a flag to indicate the queue can be used for soft commands. If this flag is set, post_lock must be acquired before posting a command to the queue. If this flag is clear, post_lock is invalid for the queue. Signed-off-by:

When using an ip6tnl device in collect_md mode, the xmit methods ignore the ipv6.src field present in skb_tunnel_info's key, both for route calculation purposes (flowi6 construction) and for assigning the packet's final ipv6h->saddr. This makes it impossible specifying a desired ipv6 local address in the encapsulating header (for example, when using tc action tunnel_key). This is also not aligned with behavior of ipip (ipv4) in collect_md mode, where the key->u.ipv4.src gets used. Fix, by assigning fl6.saddr with given key->u.ipv6.src. In case ipv6.src is not specified, ip6_tnl_xmit uses existing saddr selection code. Fixes: 8d79266b ("ip6_tunnel: add collect_md mode to IPv6 tunnels") Signed-off-by:

Allow matching on options in Geneve tunnel headers. This makes use of existing tunnel metadata support. The options can be described in the form CLASS:TYPE:DATA/CLASS_MASK:TYPE_MASK:DATA_MASK, where CLASS is represented as a 16bit hexadecimal value, TYPE as an 8bit hexadecimal value and DATA as a variable length hexadecimal value. e.g. # ip link add name geneve0 type geneve dstport 0 external # tc qdisc add dev geneve0 ingress # tc filter add dev geneve0 protocol ip parent ffff: \ flower \ enc_src_ip 10.0.99.192 \ enc_dst_ip 10.0.99.193 \ enc_key_id 11 \ geneve_opts 0102:80:1122334421314151/ffff:ff:ffffffffffffffff \ ip_proto udp \ action mirred egress redirect dev eth1 This patch adds support for matching Geneve options in the order supplied by the user. This leads to an efficient implementation in the software datapath (and in our opinion hardware datapaths that offload this feature). It is also compatible with Geneve options matching provided by the Open vSwitch kernel datapath which is relevant here as the Flower classifier may be used as a mechanism to program flows into hardware as a form of Open vSwitch datapath offload (sometimes referred to as OVS-TC). The netlink Kernel/Userspace API may be extended, for example by adding a flag, if other matching options are desired, for example matching given options in any order. This would require an implementation in the TC software datapath. And be done in a way that drivers that facilitate offload of the Flower classifier can reject or accept such flows based on hardware datapath capabilities. This approach was discussed and agreed on at Netconf 2017 in Seoul. Signed-off-by: -

Allow the existing 'dissection' of tunnel metadata to 'dissect' options already present in tunnel metadata. This dissection is controlled by a new dissector key, FLOW_DISSECTOR_KEY_ENC_OPTS. This dissection only occurs when skb_flow_dissect_tunnel_info() is called, currently only the Flower classifier makes that call. So there should be no impact on other users of the flow dissector. This is in preparation for allowing the flower classifier to match on Geneve options. Signed-off-by:

This function accidentally failed to update the data pointer, which caused the reported stats to be incorrect. Additionally, statistics which follow queue stats in the output would potentially read non-zeroed garbage data from the ethtool buffer. This occurred because the data double pointer was not dereferenced before incrementing the size. Additionally, make sure this issue is more visible by adding a WARN_ONCE to the i40e_get_ethtool_stats function. This warning will trigger whenever the data pointer is not at the expected address, similar to the check that we make in the i40e_get_stat_strings() function. Signed-off-by:

In commit 147e81ec ("i40e: Test memory before ethtool alloc succeeds") code was added to handle ring allocation on systems with low memory. It shadowed the ring parameter pointer by introducing a local ring pointer inside the for loop. Most of the code in the loop already just accessed the ring via &rx_rings[i]. Since most of the code already does this, just remove the local variable. If someone considers it worth keeping a local around, they should use it for the whole section instead of just a couple of accesses. This fixes a warning when -Wshadow is enabled Signed-off-by:

Commit c61c8fe1 ("i40e: Implement an ethtool private flag to stop LLDP in FW") added an extra for-loop which added a shadowing 'i' variable as the index. However, the local variable i already exists, and we already use it as a loop index. Additionally, at this point, there is no further use of the variable, so it's safe to simply overwrite the variable contents. This fixes a -Wshadow warning which has started being enabled on some distributions Signed-off-by:
