2022-08-26net: prestera: manage matchall and flower prioritiesMaksym Glubokiy8-0/+163
matchall rules can be added only to chain 0 and their priorities have limitations: - new matchall ingress rule's priority must be higher (lower value) than any existing flower rule; - new matchall egress rule's priority must be lower (higher value) than any existing flower rule. The opposite works for flower rule adding: - new flower ingress rule's priority must be lower (higher value) than any existing matchall rule; - new flower egress rule's priority must be higher (lower value) than any existing matchall rule. This is a hardware limitation and thus must be properly handled in driver by reporting errors to the user when newly added rule has such a priority that cannot be installed into the hardware. To achieve this, the driver must maintain both min/max matchall priorities for every flower block when user adds/deletes a matchall rule, as well as both min/max flower priorities for chain 0 for every adding/deletion of flower rules for chain 0.

2022-08-26net: prestera: acl: extract matchall logic into a separate fileSerhiy Boiko6-66/+96
This commit adds more clarity to handling of TC_CLSMATCHALL_REPLACE and TC_CLSMATCHALL_DESTROY events by calling newly added *_mall_*() handlers instead of directly calling SPAN API. This also extracts matchall rules management out of SPAN API since SPAN is a hardware module which is used to implement 'matchall egress mirred' action only.

2022-08-05octeontx2-pf: Fix NIX_AF_TL3_TL2X_LINKX_CFG register configurationNaveen Mamindlapalli2-5/+15
For packets scheduled to RPM and LBK, NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL] selects the TL3 or TL2 scheduling level as the one used for link/channel selection and backpressure. For each scheduling queue at the selected level: Setting NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG[ENA] = 1 allows the TL3/TL2 queue to schedule packets to a specified RPM or LBK link and channel. There is an issue in the code where NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL] is set to TL3 where as the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG is configured for TL2 queue in some cases. As a result packets will not transmit on that link/channel. This patch fixes the issue by configuring the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG register depending on the NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL] value.

2022-08-01octeontx2-pf: Reduce minimum mtu size to 60Subbaraya Sundeep1-1/+1
PTP messages like SYNC, FOLLOW_UP, DELAY_REQ are of size 58 bytes. Using a minimum packet length as 64 makes NIX to pad 6 bytes of zeroes while transmission. This is causing latest ptp4l application to emit errors since length in PTP header and received packet are not same. Padding upto 3 bytes is fine but more than that makes ptp4l to assume the pad bytes as a TLV. Hence reduce the size to 60 from 64.

2022-07-13net: marvell: prestera: implement software MDB entries allocationOleksandr Mazur3-2/+635
Define bridge MDB entry (software entry): - entry that get's created upon receiving MDB management events (create/delete), that inherently defines a software entry, which can be enabled (offloaded to the HW) or disabled (removed from HW). This separation is done to achieve a better highlevel management of HW resources - software MDB entry could exist, while it's not necessarily should be configured on the HW. For example: by default, the Linux behavior would not replicate multicast traffic to multicast group members if there's no active multicast router and thus - no actual multicast traffic can be received/sent. So, until multicast router appears on the system no HW configuration should be applied, although SW MDB entries should be tracked. Another example would be altering state of 'multicast enabled' on the bridge: MC_DISABLED should invoke disabling / clearing multicast groups of specified bridge on the HW, yet upon receiving 'multicast enabled' event, driver should reconfigure any existing software MDB groups on the HW. Keeping track of software MDB entries in such way makes it possible to properly react on such events.
