2020-12-08net: hns3: add priv flags support to switch limit promisc modeJian Shen7-1/+119
Currently, the tx unicast promisc is always enabled when promisc mode on. If tx unicast promisc on, a function will receive all unicast packet from other functions belong to the same port. Add a ethtool private flag to control whether enable tx unicast promisc. Then the function is able to filter the unknown unicast packets from other function.

2020-12-08net: hns3: add support for extended promiscuous commandGuojia Liao2-49/+41
For DEVICE_VERSION_V2, the hardware supports enable tx and rx promiscuous separately. But tx or rx promiscuous is active for unicast, multicast and broadcast promiscuous simultaneously. To support traffics between functions belong to the same port, we always enable tx promiscuous for broadcast promiscuous, so tx promiscuous for unicast and multicast promiscuous is also enabled. For DEVICE_VERSION_V3, the hardware decouples the above relationship. Tx unicast promiscuous, rx unicast promiscuous, tx multicast promiscuous, rx multicast promiscuous, tx broadcast promiscuous and rx broadcast promiscuous can be enabled separately. So add support for the new promiscuous command. Signed-off-by: Guojia Liao <liaoguojia@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2020-12-08net/mlx5e: Add TX port timestamp supportEran Ben Elisha9-7/+262
Transmitted packet timestamping accuracy can be improved when using timestamp from the port, instead of packet CQE creation timestamp, as it better reflects the actual time of a packet's transmit. TX port timestamping is supported starting from ConnectX6-DX hardware. Although at the original completion, only CQE timestamp can be attached, we are able to get TX port timestamping via an additional completion over a special CQ associated with the SQ (in addition to the regular CQ). Driver to ignore the original packet completion timestamp, and report back the timestamp of the special CQ completion. If the absolute timestamp diff between the two completions is greater than 1 / 128 second, ignore the TX port timestamp as it has a jitter which is too big. No skb will be generate out of the extra completion. Allocate additional CQ per ptpsq, to receive the TX port timestamp. Driver to hold an skb FIFO in order to map between transmitted skb to the two expected completions. When using ptpsq, hold double refcount on the skb, to gaurantee it will not get released before both completions arrive. Expose dedicated counters of the ptp additional CQ and connect it to the TX health reporter. This patch improves TX Hardware timestamping offset to be less than 40ns at a 100Gbps line rate, compared to 600ns before. With that, making our HW compliant with G.8273.2 class C, and allow Linux systems to be deployed in the 5G telco edge, where this standard is a must.

Add TX PTP port object support for better TX timestamping accuracy. Currently, driver supports CQE based TX port timestamp. Device also offers TX port timestamp, which has less jitter and better reflects the actual time of a packet's transmit. Define new driver layout called ptpsq, on which driver will create SQs that will support TX port timestamp for their transmitted packets. Driver to identify PTP TX skbs and steer them to these dedicated SQs as part of the select queue ndo. Driver to hold ptpsq per TC and report them at netif_set_real_num_tx_queues(). Add support for all needed functionality in order to xmit and poll completions received via ptpsq. Add ptpsq to the TX reporter recover, diagnose and dump methods. Creation of ptpsqs is disabled by default, and can be enabled via tx_port_ts private flag.

hclge_dbg_reg_info[] is defined as an array of packed structure accidentally. However, this array contains pointers, which are no longer aligned naturally, and cannot be relocated on PPC64. Hence, when compile-testing this driver on PPC64 with CONFIG_RELOCATABLE=y (e.g. PowerPC allyesconfig), there will be some warnings. Since each field in structure hclge_qos_pri_map_cmd and hclge_dbg_bitmap_cmd is type u8, the pragma packed is unnecessary for these two structures as well, so remove the pragma packed in hclge_debugfs.h to fix this issue, and this increases hclge_dbg_reg_info[] by 4 bytes per entry.

2020-12-05net: mscc: ocelot: fix dropping of unknown IPv4 multicast on SevilleVladimir Oltean2-4/+6
The current assumption is that the felix DSA driver has flooding knobs per traffic class, while ocelot switchdev has a single flooding knob. This was correct for felix VSC9959 and ocelot VSC7514, but with the introduction of seville VSC9953, we see a switch driven by felix.c which has a single flooding knob. So it is clear that we must do what should have been done from the beginning, which is not to overwrite the configuration done by ocelot.c in felix, but instead to teach the common ocelot library about the differences in our switches, and set up the flooding PGIDs centrally. The effect that the bogus iteration through FELIX_NUM_TC has upon seville is quite dramatic. ANA_FLOODING is located at 0x00b548, and ANA_FLOODING_IPMC is located at 0x00b54c. So the bogus iteration will actually overwrite ANA_FLOODING_IPMC when attempting to write ANA_FLOODING[1]. There is no ANA_FLOODING[1] in sevile, just ANA_FLOODING. And when ANA_FLOODING_IPMC is overwritten with a bogus value, the effect is that ANA_FLOODING_IPMC gets the value of 0x0003CF7D: MC6_DATA = 61, MC6_CTRL = 61, MC4_DATA = 60, MC4_CTRL = 0. Because MC4_CTRL is zero, this means that IPv4 multicast control packets are not flooded, but dropped. An invalid configuration, and this is how the issue was actually spotted.

2020-12-04nfp: Replace zero-length array with flexible-array memberSimon Horman2-2/+2
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members"[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

2020-12-04net/mlx5: Register mlx5 devices to auxiliary virtual busLeon Romanovsky4-8/+302
Create auxiliary devices under new virtual bus. This will replace the custom-made mlx5 ->add()/->remove() interfaces and next patches will fill the missing callback and remove the old interface logic. The attachment of auxiliary drivers to the devices is possible in 1-to-1 manner only and it requires us to create device for every protocol, so that device (module) will be able to connect to it.
