Instead of having two dsa_ds_find_port_dn (which returns a bool) and dsa_dst_find_port_dn (which returns a switch) functions, provide a more explicit dsa_tree_find_port_by_node function which returns a matching port.

The dsa_dsa_port_apply and dsa_cpu_port_apply functions do exactly the same. The dsa_user_port_apply function does not try to register a fixed link but try to create a slave. This commit factorizes and scopes all that in two convenient dsa_port_setup and dsa_port_teardown functions. It won't hurt to register a devlink_port for unused port as well.

This patches brings no functional changes. It removes the unused dst argument from the dsa_ds_apply and dsa_ds_unapply functions, rename them to dsa_switch_setup and dsa_switch_teardown for a more explicit scope. This clarifies the steps of the setup or teardown of a switch fabric. Signed-off-by: NVivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This commit provides better scope for the DSA tree setup and teardown functions. It renames the "applied" bool to "setup" and print a message when the tree is setup, as it is done during teardown.

The dsa_dst_parse function called just before dsa_dst_apply does not parse the tree but does only one thing: it assigns the default CPU port to dst->cpu_dp and to each user ports. This patch simplifies this by calling a dsa_tree_setup_default_cpu function at the beginning of dsa_dst_apply directly. A dsa_port_is_user helper is added for convenience.

Timestamps in pktgen are currently retrieved using the deprecated do_gettimeofday() function that wraps its signed 32-bit seconds in 2038 (on 32-bit architectures) and requires a division operation to calculate microseconds. The pktgen header is also defined with the same limitations, hardcoding to a 32-bit seconds field that can be interpreted as unsigned to produce times that only wrap in 2106. Whatever code reads the timestamps should be aware of that problem in general, but probably doesn't care too much as we are mostly interested in the time passing between packets, and that is correctly represented. Using 64-bit nanoseconds would be cheaper and good for 584 years. Using monotonic times would also make this unambiguous by avoiding the overflow, but would make it harder to correlate to the times with those on remote machines. Either approach would require adding a new runtime flag and implementing the same thing on the remote side, which we probably don't want to do unless someone sees it as a real problem. Also, this should be coordinated with other pktgen implementations and might need a new magic number. For the moment, I'm documenting the overflow in the source code, and changing the implementation over to an open-coded ktime_get_real_ts64() plus division, so we don't have to look at it again while scanning for deprecated time interfaces.

Jiri Pirko says: ==================== qdisc RED offload Nogah says: Add an offload support for RED qdisc for mlxsw driver. The first patch adds the ability to offload RED qdisc by using ndo_setup_tc. It gives RED three commands, to offload, change or delete the qdisc, to get the qdisc generic stats and to get it's RED xstats. There is no enforcement on a driver to offload or not offload the qdisc and it is up to the driver to decide. RED qdisc is first being created and only later graft to a parent (unless it is a root qdisc). For that reason the return value of the offload replace command that is called in the init process doesn't reflect actual offload state. The offload state is determined in the dump function so it can be reflected to the user. This function is also responsible for stats update. The patchses 2-3 change the name of TC_SETUP_MQPRIO & TC_SETUP_CBS to match with the new convention of QDISC prefix. The rest of the patchset is driver support for the qdisc. Currently only as root qdisc that is being set on the default traffic class. It supports only the following parameters of RED: min, max, probability and ECN mode. Limit and burst size related params are being ignored at this moment. --- v7->v8 internal: (external RFC->v1) - patch 1/9: - unite the offload and un-offload functions - clean the OFFLOAD flag when the qdisc in not offloaded - patch 2/9: - minor change to avoid a conflict - patch 5/9: - check for bad min/max values - clean the offloaded qdisc after a bad config call ==================== Signed-off-by: NDavid S.
