2019-07-01mlxsw: core: Add support for using SKB control bufferPetr Machata1-0/+2
The SKB control buffer is useful (and used) for bookkeeping of information related to that SKB. Add helpers so that the mlxsw driver(s) can safely use the buffer as well. The structure is currently empty, individual users will add members to it as necessary. Note that SKB allocation functions already clear the buffer, so the cleanup is only necessary when ndo_start_xmit is called.

2017-01-12mlxsw: switchx2: Fix memory leak at skb reallocationArkadi Sharshevsky1-0/+1
During transmission the skb is checked for headroom in order to add vendor specific header. In case the skb needs to be re-allocated, skb_realloc_headroom() is called to make a private copy of the original, but doesn't release it. Current code assumes that the original skb is released during reallocation and only releases it at the error path which causes a memory leak. Fix this by adding the original skb release to the main path.

2016-11-25mlxsw: 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.

2016-11-25mlxsw: 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.

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.

2016-10-28mlxsw: Move PCI id table definitions into driver modulesJiri Pirko1-4/+30
So far, mlxsw_pci.ko is the module that registers PCI table for all drivers (spectrum and switchx2). That is problematic for example with dracut. Since mlxsw_spectrum.ko and mlxsw_switchx2.ko are loaded dynamically from within mlxsw_core.ko, dracut does not have track of them and avoids them from being included in initramfs. So make this in an ordinary way and define the PCI tables in individual driver modules, so it can be properly loaded and included in dracut initramfs image. As a side effect, this patch could remove no longer necessary driver "kind" strings which were used to link PCI ids with individual mlxsw drivers.

Instead of that, pass mlxsw_core and use a helper to get driver priv from driver code. Looks much cleaner that way. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
