* net: ethernet: ti: am65-cpsw-qos: Add Frame Preemption MAC Merge supportRoger Quadros2023-12-236-2/+456
| | | | | | | | | | | | | | | | | | | | | | | | Add driver support for viewing / changing the MAC Merge sublayer parameters and seeing the verification state machine's current state via ethtool. As hardware does not support interrupt notification for verification events we resort to polling on link up. On link up we try a couple of times for verification success and if unsuccessful then give up. The Frame Preemption feature is described in the Technical Reference Manual [1] in section: 12.3.1.4.6.7 Intersperced Express Traffic (IET – P802.3br/D2.0) Due to Silicon Errata i2208 [2] we set limit min IET fragment size to 124 (excluding 4 bytes mCRC).

* net: ethernet: ti: am65-cpsw: add mqprio qdisc offload in channel modeGrygorii Strashko2023-12-234-4/+278
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds MQPRIO Qdisc offload in full 'channel' mode which allows not only setting up pri:tc mapping, but also configuring TX shapers (rate-limiting) on external port FIFOs. The MQPRIO Qdisc offload is expected to work with or without VLAN/priority tagged packets. The CPSW external Port FIFO has 8 Priority queues. The rate-limit can be set for each of these priority queues. Which Priority queue a packet is assigned to depends on PN_REG_TX_PRI_MAP register which maps header priority to switch priority. The header priority of a packet is assigned via the RX_PRI_MAP_REG which maps packet priority to header priority. The packet priority is either the VLAN priority (for VLAN tagged packets) or the thread/channel offset. For simplicity, we assign the same priority queue to all queues of a Traffic Class so it can be rate-limited correctly. Configuration example: ethtool -L eth1 tx 5 ethtool --set-priv-flags eth1 p0-rx-ptype-rrobin off tc qdisc add dev eth1 parent root handle 100: mqprio num_tc 3 \ map 0 0 1 2 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 1@1 1@2 hw 1 mode channel \ shaper bw_rlimit min_rate 0 100mbit 200mbit max_rate 0 101mbit 202mbit tc qdisc replace dev eth2 handle 100: parent root mqprio num_tc 1 \ map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 queues 1@0 hw 1 ip link add link eth1 name eth1.100 type vlan id 100 ip link set eth1.100 type vlan egress 0:0 1:1 2:2 3:3 4:4 5:5 6:6 7:7 In the above example two ports share the same TX CPPI queue 0 for low priority traffic. 3 traffic classes are defined for eth1 and mapped to: TC0 - low priority, TX CPPI queue 0 -> ext Port 1 fifo0, no rate limit TC1 - prio 2, TX CPPI queue 1 -> ext Port 1 fifo1, CIR=100Mbit/s, EIR=1Mbit/s TC2 - prio 3, TX CPPI queue 2 -> ext Port 1 fifo2, CIR=200Mbit/s, EIR=2Mbit/s Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Roger Quadros <rogerq@kernel.org> Reviewed-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

* selftests: forwarding: ethtool_mm: support devices with higher rx-min-frag-sizeVladimir Oltean2023-12-231-2/+35
| | | | | | | | | | | | | | | | | | | | Some devices have errata due to which they cannot report ETH_ZLEN (60) in the rx-min-frag-size. This was foreseen of course, and lldpad has logic that when we request it to advertise addFragSize 0, it will round it up to the lowest value that is _actually_ supported by the hardware. The problem is that the selftest expects lldpad to report back to us the same value as we requested. Make the selftest smarter by figuring out on its own what is a reasonable value to expect.

Let's replace tb->owners iteration in inet_csk_bind_conflict() with two iterations over tb2->owners and tb2->deathrow. This can be done safely under bhash's lock because socket insertion/ deletion in bhash2 happens with bhash's lock held. Note that twsk_for_each_bound_bhash() will be removed later.

However, bhash itself need not have sockets. If we link each bhash2 bucket to the corresponding bhash bucket, we can iterate the same set of the sockets from bhash2 via bhash.

It's then "common" in the code and hopefully future change-sets will see the context and do-the-right-thing. This conversion was done with a coccinelle script which is mentioned in the commit messages. Generally there were only a couple conversions that were "undone" after the automatic changes because they tried to convert a non-contiguous mask. Patch 1 is required at the beginning of this series to fix a "forever" issue in the e1000e driver that fails the compilation test after conversion because the shift / mask was out of range. The second patch just adds all the new #includes in one go. The patch titled: "ice: fix pre-shifted bit usage" is needed to allow the use of the FIELD_* macros and fix up the unexpected "shifts included" defines found while creating this series. The rest are the conversion to use FIELD_PREP()/FIELD_GET(), and the occasional leXX_{get,set,encode}_bits() call, as suggested by Alex. ==================== Signed-off-by: David S.

Rename the defines and set them to the "pre-shifted values" so they match the template the driver normally uses for masks and the member bits of the mask, which also allows the driver to use FIELD_PREP correctly with these values.
