2021-05-18mlxsw: Remove Mellanox SwitchX-2 ASIC supportAmit Cohen1-1691/+0
Initial support for the Mellanox SwitchX-2 ASIC was added in July 2015. Since then all development efforts shifted towards the Mellanox Spectrum ASICs and development of this driver stopped beside trivial fixes and refactoring. Therefore, the driver does not support any switch offloads and simply traps all traffic to the CPU, rendering it irrelevant for deployment. In addition, support for this ASIC was dropped by Mellanox a few years ago. Given the driver is not used by any users and that there is no intention of investing in its development, remove it from the kernel.

2021-02-27mlxsw: spectrum_ethtool: Add an external speed to PTYS registerDanielle Ratson1-1/+2
Currently, only external bits are added to the PTYS register, whereas there is one external bit that is wrongly marked as internal, and so was recently removed from the register. Add that bit to the PTYS register again, as this bit is no longer internal. Its removal resulted in '100000baseLR4_ER4/Full' link mode no longer being supported, causing a regression on some setups.

2020-08-25mlxsw: spectrum_ethtool: Remove internal speeds from PTYS registerDanielle Ratson1-24/+1
The PTYS register is used to report and configure the port type and speed. Currently, internal bits in the register are used the same way other bits are used. Using the internal bits can cause bad parameter firmware errors. For example, trying to write to internal bit 25 returns: EMAD reg access failed (tid=53e2bffa00004310,reg_id=5004(ptys),type=write,status=7(bad parameter)) Remove the internal bits from the PTYS register, so that it is no longer possible to pass them to firmware.

2020-01-15mlxsw: switchx2: Do not modify cloned SKBs during xmitIdo Schimmel1-11/+6
The driver needs to prepend a Tx header to each packet it is transmitting. The header includes information such as the egress port and traffic class. The addition of the header requires the driver to modify the SKB's header and therefore it must not be shared. Otherwise, we risk hitting various race conditions. For example, when a packet is flooded (cloned) by the bridge driver to two switch ports swp1 and swp2: t0 - mlxsw_sp_port_xmit() is called for swp1. Tx header is prepended with swp1's port number t1 - mlxsw_sp_port_xmit() is called for swp2. Tx header is prepended with swp2's port number, overwriting swp1's port number t2 - The device processes data buffer from t0. Packet is transmitted via swp2 t3 - The device processes data buffer from t1. Packet is transmitted via swp2 Usually, the device is fast enough and transmits the packet before its Tx header is overwritten, but this is not the case in emulated environments. Fix this by making sure the SKB's header is writable by calling skb_cow_head(). Since the function ensures we have headroom to push the Tx header, the check further in the function can be removed. v2: * Use skb_cow_head() instead of skb_unshare() as suggested by Jakub * Remove unnecessary check regarding headroom Fixes: 31557f0f9755 ("mlxsw: Introduce Mellanox SwitchX-2 ASIC support") Signed-off-by: Ido Schimmel <idosch@mellanox.com> Reported-by: Shalom Toledo <shalomt@mellanox.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2019-08-29mlxsw: Remove 56G speed supportAmit Cohen1-6/+0
Commit 275e928f1911 ("mlxsw: spectrum: Prevent force of 56G") prevented the driver from setting a speed of 56G when auto-negotiation is off. This is the only speed supported by mlxsw that cannot be set when auto-negotiation is off, which makes it difficult to write generic tests. Further, the speed is not supported by newer ASICs such as Spectrum-2 and to the best of our knowledge it is not used by current users. Therefore, remove 56G support from mlxsw.

2016-11-26mlxsw: Create a different trap group list for each deviceNogah Frankel1-4/+4
Trap groups can be used to control traps priority, both in terms of which trap "wins" if a packet matches two traps (priority) and in terms of packets from which trap group will be scheduled to the cpu first (tc). They can also be used to set rate limiters (policers) on them (will be added in the next patches). Currently, we support two trap groups. In Spectrum we want a better resolution, so every protocol / flow will have a different trap group, so we can control its parameters separately. Once the policers will be implemented, it will also allow us limit the rate of each protocol by itself. This patch change the trap group list to include: * the emad trap group, which is shared for all the devices. * Switchx2's trap groups, which are a copy of the current trap groups. * Spectrum's new trap groups, in order to match the above guidelines. (Switchib is using only the emad trap group, so it require no changes). This patch also includes new configuration for Spectrum's trap groups, with primary priority order within them.

2016-11-26mlxsw: Change trap groups settingNogah Frankel1-3/+21
Trap groups have many options which we currently set to default values. In the next patches we will use many of them with non-default values. Some of these options have no default value, so this patch sets them as params for the trap group set function. Others almost always use the same values, so the set function will use this default values. In the rare cases when they will need to be with other values, these values can be set directly (using the macros for fields in registers). Parameters without default value: TC - the traffic class for packets that hit this trap group. (old default is the max tc) priority - if one packet hits multiple trap groups, the group with the higher priority will "catch" it. (old default is 0) policer - limit rate policer (old default is disabled) Default parameters: swid - switch id, relevant for the emad trap only, ignored on Spectrum. (new default is 0) rdq - CPU receive descriptor queue (new default is identical to trap group id) Signed-off-by: Nogah Frankel <nogahf@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

Do it in a same way we do it in spectrum. Check if port is usable first and only in that case create a port instance.

2016-10-30mlxsw: core: Zero payload buffers for couple of registersElad Raz1-1/+1
We recently discovered a bug in the firmware in which a field's length in one of the registers was incorrectly set. This caused the firmware to access garbage data that wasn't initialized by the driver and therefore emit error messages. While the bug is already fixed and the driver usually zeros the buffers passed to the firmware, there are a handful of cases where this isn't done. Zero the buffer in these cases and prevent similar bugs from recurring, as they tend to be hard to debug.
