Simplify the endpoint sanity check by letting core verify that the required endpoints are present. Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Johan Hovold <johan@kernel.org>
2020-01-23USB: serial: ir-usb: make set_termios synchronousJohan Hovold
Use a synchronous usb_bulk_msg() when switching link speed in set_termios(). This way we do not need to keep track of outstanding URBs in order to be able to stop them at close. Note that there's no need to set URB_ZERO_PACKET as the one-byte transfer will always be short.

2020-01-23USB: serial: ir-usb: fix IrLAP framingJohan Hovold
Commit f4a4cbb2047e ("USB: ir-usb: reimplement using generic framework") switched to using the generic write implementation which may combine multiple write requests into larger transfers. This can break the IrLAP protocol where end-of-frame is determined using the USB short packet mechanism, for example, if multiple frames are sent in rapid succession.

2020-01-23USB: serial: ir-usb: fix link-speed handlingJohan Hovold
Commit e0d795e4f36c ("usb: irda: cleanup on ir-usb module") added a USB IrDA header with common defines, but mistakingly switched to using the class-descriptor baud-rate bitmask values for the outbound header. This broke link-speed handling for rates above 9600 baud, but a device would also be able to operate at the default 9600 baud until a link-speed request was issued (e.g. using the TCGETS ioctl).

2020-01-23USB: serial: ir-usb: add missing endpoint sanity checkJohan Hovold
Add missing endpoint sanity check to avoid dereferencing a NULL-pointer on open() in case a device lacks a bulk-out endpoint. Note that prior to commit f4a4cbb2047e ("USB: ir-usb: reimplement using generic framework") the oops would instead happen on open() if the device lacked a bulk-in endpoint and on write() if it lacked a bulk-out endpoint.

In order to support all of the supported stats that are available in legacy mode for switchdev uplink representors, convert rep stats infrastructure to reuse struct mlx5e_stats_grp that is already used when device is in legacy mode. Refactor rep code to use array of mlx5e_stats_grp structures (constructed using macros provided by stats infra) to fill/update stats, instead of fixed hardcoded set of values.

2020-01-22net/mlx5e: Add mlx5e_flower_parse_meta supportwenxu
In the flowtables offload all the devices in the flowtables share the same flow_block. An offload rule will be installed on all the devices. This scenario is not correct. It is no problem if there are only two devices in the flowtable, The rule with ingress and egress on the same device can be reject by driver. But more than two devices in the flowtable will install the wrong rules on hardware. For example: Three devices in a offload flowtables: dev_a, dev_b, dev_c A rule ingress from dev_a and egress to dev_b: The rule will install on device dev_a. The rule will try to install on dev_b but failed for ingress and egress on the same device. The rule will install on dev_c. This is not correct. The flowtables offload avoid this case through restricting the ingress dev with FLOW_DISSECTOR_KEY_META. So the mlx5e driver also should support the FLOW_DISSECTOR_KEY_META parse.

It is based on EricD recent fixes to the kernel tcp_cubic. [1] 2. The bpf jiffies reading helper is inlined by the verifier. Different from the earlier version, it only reads jiffies alone and does not do usecs/jiffies conversion. 3. The bpf .kconfig map is used to read CONFIG_HZ. [1]: https://patchwork.ozlabs.org/cover/1215066/ v3: - Remove __weak from CONFIG_HZ in patch 3. (Andrii) v2: - Move inlining to fixup_bpf_calls() in patch 1. (Daniel) - It is inlined for 64 BITS_PER_LONG and jit_requested as the map_gen_lookup().

This patch adds a bpf_cubic example. Some highlights: 1. CONFIG_HZ .kconfig map is used. 2. In bictcp_update(), calculation is changed to use usec resolution (i.e. USEC_PER_JIFFY) instead of using jiffies. Thus, usecs_to_jiffies() is not used in the bpf_cubic.c. 3. In bitctcp_update() [under tcp_friendliness], the original "while (ca->ack_cnt > delta)" loop is changed to the equivalent "ca->ack_cnt / delta" operation.
