Antoine Tenart says: ==================== net: phy: split the mscc driver This is a proposal to split the MSCC PHY driver, as its code base grew a lot lately (it's already 3800+ lines). It also supports features requiring a lot of code (MACsec), which would gain in being split from the driver core, for readability and maintenance. This is also done as other features should be coming later, which will also need lots of code addition. This series shouldn't change the way the driver works. I checked, and there were no patch pending on this driver. This change was done on top of all the modifications done on this driver in net-next. Since v2: - Defined inline functions as static inline. - Fixed a locking issue reported by Kbuild. Since v1: - Moved more definitions into the mscc_macsec.h header. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2020-03-15net: phy: mscc: split the driver into separate filesAntoine Tenart5-1462/+1515
This patch splits the MSCC driver into separate files, per functionality, to improve readability and maintenance as the codebase grew a lot. The MACsec code is moved to a dedicated mscc_macsec.c file, the mscc.c file is renamed to mscc_main.c to keep the driver binary to be named mscc and common definition are put into a new mscc.h header. Most of the code was just moved around, except for a few exceptions: - Header inclusions were reworked to only keep what's needed. - Three helpers were created in the MACsec code, to avoid #ifdef's in the main C file: vsc8584_macsec_init, vsc8584_handle_macsec_interrupt and vsc8584_config_macsec_intr.

2020-03-15Merge branch 'RED-Introduce-an-ECN-tail-dropping-mode'David S. Miller9-20/+371
Petr Machata says: ==================== RED: Introduce an ECN tail-dropping mode When the RED qdisc is currently configured to enable ECN, the RED algorithm is used to decide whether a certain SKB should be marked. If that SKB is not ECN-capable, it is early-dropped. It is also possible to keep all traffic in the queue, and just mark the ECN-capable subset of it, as appropriate under the RED algorithm. Some switches support this mode, and some installations make use of it. There is currently no way to put the RED qdiscs to this mode. Therefore this patchset adds a new RED flag, TC_RED_TAILDROP. When the qdisc is configured with this flag, non-ECT traffic is enqueued (and tail-dropped when the queue size is exhausted) instead of being early-dropped. Unfortunately, adding a new RED flag is not as simple as it sounds. RED flags are passed in tc_red_qopt.flags. However RED neglects to validate the flag field, and just copies it over wholesale to its internal structure, and later dumps it back. A broken userspace can therefore configure a RED qdisc with arbitrary unsupported flags, and later expect to see the flags on qdisc dump. The current ABI thus allows storage of 5 bits of custom data along with the qdisc instance. GRED, SFQ and CHOKE qdiscs are in the same situation. (GRED validates VQ flags, but not the flags for the main queue.) E.g. if SFQ ever needs to support TC_RED_ADAPTATIVE, it needs another way of doing it, and at the same time it needs to retain the possibility to store 6 bits of uninterpreted data. For RED, this problem is resolved in patch #2, which adds a new attribute, and a way to separate flags from userbits that can be reused by other qdiscs. The flag itself and related behavioral changes are added in patch To test the new feature, patch #1 first introduces a TDC testsuite that covers the existing RED flags. Patch #5 later extends it with taildrop coverage. Patch #6 contains a forwarding selftest for the offloaded datapath. To test the SW datapath, I took the mlxsw selftest and adapted it in mostly obvious ways. The test is stable enough to verify that RED, ECN and ECN taildrop actually work. However, I have no confidence in its portability to other people's machines or mildly different configurations. I therefore do not find it suitable for upstreaming. GRED and CHOKE can use the same method as RED if they ever need to support extra flags. SFQ uses the length of TCA_OPTIONS to dispatch on binary control structure version, and would therefore need a different approach. v2: - Patch #1 - Require nsPlugin in each RED test - Match end-of-line to catch cases of more flags reported than requested - Patch #2: - Replaced with another patch. - Patch #3: - Fix red_use_taildrop() condition in red_enqueue switch for probabilistic case. - Patch #5: - Require nsPlugin in each RED test - Match end-of-line to catch cases of more flags reported than requested - Add a test for creation of non-ECN taildrop, which should fail ==================== Signed-off-by: David S.

Extend RED testsuite to cover the new nodrop mode of RED-ECN. This test is really similar to ECN test, diverging only in the last step, where UDP traffic should go to backlog instead of being dropped. Thus extract a common helper, ecn_test_common(), make do_ecn_test() into a relatively simple wrapper, and add another one, do_ecn_nodrop_test().

2020-03-15mlxsw: spectrum_qdisc: Offload RED ECN nodrop modePetr Machata1-4/+5
RED ECN nodrop mode means that non-ECT traffic should not be early-dropped, but enqueued normally instead. In Spectrum systems, this is achieved by disabling CWTPM.ew (enable WRED) for a given traffic class. So far CWTPM.ew was unconditionally enabled. Instead disable it when the RED qdisc is in nodrop mode. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-03-15net: sched: Allow extending set of supported RED flagsPetr Machata3-3/+89
The qdiscs RED, GRED, SFQ and CHOKE use different subsets of the same pool of global RED flags. These are passed in tc_red_qopt.flags. However none of these qdiscs validate the flag field, and just copy it over wholesale to internal structures, and later dump it back. (An exception is GRED, which does validate for VQs -- however not for the main setup.) A broken userspace can therefore configure a qdisc with arbitrary unsupported flags, and later expect to see the flags on qdisc dump. The current ABI therefore allows storage of several bits of custom data to qdisc instances of the types mentioned above. How many bits, depends on which flags are meaningful for the qdisc in question. E.g. SFQ recognizes flags ECN and HARDDROP, and the rest is not interpreted. If SFQ ever needs to support ADAPTATIVE, it needs another way of doing it, and at the same time it needs to retain the possibility to store 6 bits of uninterpreted data. Likewise RED, which adds a new flag later in this patchset. To that end, this patch adds a new function, red_get_flags(), to split the passed flags of RED-like qdiscs to flags and user bits, and red_validate_flags() to validate the resulting configuration. It further adds a new attribute, TCA_RED_FLAGS, to pass arbitrary flags. Signed-off-by: Petr Machata <petrm@mellanox.com> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-03-14net/mlx5: E-Switch, Introduce per vport configuration for eswitch modesBodong Wang3-108/+111
Both legacy and offload modes require vport setup, only offload mode requires rep setup. Before this patch, vport and rep operations are separated applied to all relevant vports in different stages. Change to use per vport configuration, so that vport and rep operations are modularized per vport.

2020-03-14net/mlx5: E-switch, Make vport setup/cleanup sequence symmetricBodong Wang1-48/+53
Vport enable and disable sequence is incorrect. It should be: enable() esw_vport_setup_acl, esw_vport_setup, esw_vport_enable_qos. disable() esw_vport_disable_qos, esw_vport_cleanup, esw_vport_cleanup_acl. Instead of having two setup functions for port and acl, merge acl setup to port setup function.

Rename esw_apply_vport_config() to esw_vport_setup(), and add new helper function esw_vport_cleanup() to make them symmetric. Signed-off-by: Bodong Wang <bodong@mellanox.com> Reviewed-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
2020-03-14net/mlx5: E-Switch, Remove redundant warning when QoS enable failedBodong Wang1-3/+1
esw_vport_enable_qos can return error in cases below: 1. QoS is already enabled. Warnning is useless in this case. 2. Create scheduling element cmd failed. There is already a warning. Remove the redundant warnning if esw_vport_enable_qos returns err.
