Jakub Kicinski says: ==================== nfp: abm: RED/MQ qdisc offload This is second batch of advanced buffer management nfp driver changes. This series adds the qdisc offload. Support for a very simple subset of RED qdisc offload is added as needed for DCTCP ECN marking (min and max thresholds set to the same value). The first two patches fix glitches introduced by the previous series. We have to be careful about phys_port_name handling, because VFs share the same code path, and some user space may get confused by the names we chose. Since unlike previous offloads we can report the queue backlog both in bytes and packets we need to adjust how statistics are added up in the core (patch 6). There are some extra statistics we want to expose which don't fit into TC stats, namely counts of packets which have been fast- -forwarded without getting enqueued because there was no contention and number of packets that were ever queued (sum of all momentary backlogs). We expose those through ethtool stats (patches 8 and 9). Remaining 5 patches add MQ offload - to be able to set different configurations on different queues. Representors are made multi- -queue and we add offload support to MQ. MQ stats are added up before calling ->dump qdiscs on the children, and therefore don't include updated offload values. To avoid clearly incorrect stats MQ is made to also request stats update from offloads. This way we can correct the diff at the driver level. ==================== Signed-off-by: -

MQ doesn't hold any statistics on its own, however, statistic from offloads are requested starting from the root, hence MQ will read the old values for its sums. Call into the drivers, because of the additive nature of the stats drivers are aware of how much "pending updates" they have to children of the MQ. Since MQ reset its stats on every dump we can simply offset the stats, predicting how stats of offloaded children will change. Signed-off-by:

Jakub Kicinski authored
mq offload is trivial, we just need to let the device know that the root qdisc is mq. Alternative approach would be to export qdisc_lookup() and make drivers check the root type themselves, but notification via ndo_setup_tc is more in line with other qdiscs. Note that mq doesn't hold any stats on it's own, it just adds up stats of its children. Signed-off-by:

Some drivers are using a bare number inside phys_port_name as VF id and OpenStack's regexps will pick it up. We can't use a bare number for your vNICs, prefix the names with 'n'. Signed-off-by:

After recent change we started returning 0 from ndo_get_phys_port_name for VFs. The name parameter for ndo_get_phys_port_name is not initialized by the stack so this can lead to a crash. We should have kept returning -EOPNOTSUPP in the first place. Signed-off-by:

Saeed Mahameed says: ==================== mlx5e-updates-2018-05-25 This series includes updates for mlx5e netdev driver. 1) Allowr flow based VF vport mirroring under sriov switchdev scheme, added support for offloading the TC mirred mirror sub-action, from Chris Mi. ================= From: Or Gerlitz <ogerlitz@mellanox.com> The user will typically set the actions order such that the mirror port (mirror VF) sees packets as the original port (VF under mirroring) sent them or as it will receive them. In the general case, it means that packets are potentially sent to the mirror port before or after some actions were applied on them. To properly do that, we follow on the exact action order as set for the flow and make sure this will also be the case when we program the HW offload. If all the actions should apply before forwarding to the mirror and dest port, mirroring is just multicasting to the two vports. Otherwise, we split the TC flow to two HW rules, where the 1st applies only the actions needed up to the mirror (if there are such) and the 2nd the rest of the actions plus the forwarding to the dest vport. ================= 2) Move to order-0 only allocations (using fragmented work queues) for all work queues used by the driver, RX and TX descriptor rings (RQs, SQs and Completion Queues (CQs)), from Tariq Toukan. 3) Avoid resetting netdevice statistics on netdevice state changes, from Eran Ben Elisha. ==================== Signed-off-by: -

bpfilter_process_sockopt is a callback that gets called from ip_setsockopt() and ip_getsockopt(). However, when CONFIG_INET is disabled, it never gets called at all, and assigning a function to the callback pointer results in a link failure: net/bpfilter/bpfilter_kern.o: In function `__stop_umh': bpfilter_kern.c:(.text.unlikely+0x3): undefined reference to `bpfilter_process_sockopt' net/bpfilter/bpfilter_kern.o: In function `load_umh': bpfilter_kern.c:(.init.text+0x73): undefined reference to `bpfilter_process_sockopt' Since there is no caller in this configuration, I assume we can simply make the assignment conditional.

In the previous implementation of led control for fibre port , parses the port speed configuration, checks the link status and traffic status per second, and updates the blink status of link led, traffic led and speed led. Now, the firmware takes responsibility to handle the led, the dirver just needs to deal with locate command. So the codes for link led, traffic led and speed led are useless now. This patch removes these redundant codes. Signed-off-by:

When we down the port, some packets are left in TX/RX buffer. When we up the port again, these old packets are forwarded to protocol stack or are sent to internet. It will make some problem. TX/RX buffer should be cleared when stopping port. This patch adds some function to ensure the buffer is clean when port is started. We should clear the rings when clients are being un-initialized as well. Fixes: 76ad4f0e ("net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC") Signed-off-by:

RX Buffer Descriptor contains a VALID bit which indicates if the BD is valid and has some data. This field is set by HNS3 hardware to intimate the driver of some valid data present in the BD. nd should be reset by the driver when BD is being used again.

Hardware Revision(0x21) Buffer Descriptor adds a field STRP_TAGP for vlan stripped processed indication. STRP_TAGP field has 2 bits, bit 0 is stripped indication of the vlan tag in outer vlan tag field, bit 1 is stripped indication of the vlan tag in inner vlan tag field. For each bit, 0 indicates the tag is not stripped and 1 indicates the tag is stripped. This patch adds STRP_TAGP support for revision(0x21), and does not change the revision(0x20) action.

In the latest revision of the hardware, if a packet is spanning across multiple BDs then only VLD bit and current data size info is valid in each BD, and rest of the information is only valid in the last BD of the packet. In such case we should make sure we are fetching RX packet size from the first descriptor and information like VLAN should be fetched from last BD. Signed-off-by:

The struct Qdisc has a lot of holes, especially after commit a53851e2 ("net: sched: explicit locking in gso_cpu fallback"), which as a side effect, moved the fields just after 'busylock' on a new cacheline. Since both 'padded' and 'refcnt' are not updated frequently, and there is a hole before 'gso_skb', we can move such fields there, saving a cacheline without any performance side effect. Before this commit: pahole -C Qdisc net/sche/sch_generic.o # ... /* size: 384, cachelines: 6, members: 25 */ /* sum members: 236, holes: 3, sum holes: 92 */ /* padding: 56 */ After this commit: pahole -C Qdisc net/sche/sch_generic.o # ... /* size: 320, cachelines: 5, members: 25 */ /* sum members: 236, holes: 2, sum holes: 28 */ /* padding: 56 */ Signed-off-by:

SIMCOM are reusing a single device ID for many (all of their?) different modems, based on different chipsets and firmwares. Newer Qualcomm chipset generations require setting DTR to wake the QMI function. The SIM7600E modem is using such a chipset, making it fail to work with this driver despite the device ID match. Fix by unconditionally enabling the SET_DTR quirk for all SIMCOM modems using this specific device ID. This is similar to what we already have done for another case of device IDs recycled over multiple chipset generations: 14cf4a77 ("drivers: net: usb: qmi_wwan: add QMI_QUIRK_SET_DTR for Telit PID 0x1201") Initial testing on an older SIM7100 modem shows no immediate side effects.
