      Mellanox: Add new mlxsw_spectrum firmware xx.2008.2946 · da416b04
      Petr Machata authored 
      

Add latest verified version of Mellanox Spectrum-family switch firmware,
for Spectrum (13.2008.2946), Spectrum-2 (29.2008.2946) and Spectrum-3
(30.2008.2946).

The following issues have been fixed:

- A Spectrum-2 issue where control traffic generated on the switch would not
  egress a front panel port.
- Minimum shaper would not guarantee the requested bandwidth if the configured
  rate is 100Gbps+.
- On Spectrum-1, when bulk-updating FDB, a multicast tunnel entry update would
  be corrupted, and a unicast entry would not change VID.
- When ECMP or LAG are in symmetric hash mode, a packet would be steered to the
  wrong port.
- Obtaining activity for MC routes would sometimes exhibit a latency of >1us
  on Spectrum-3.

The following new features are available:

- Elephant & mice flow detection
- Register PMTDB, for querying of possible split-port scenarios
- Router interface profiles, which relax the requirement that all router
  interfaces have the same MAC address prefix.

Add latest verified version of Mellanox Spectrum-family switch firmware,
for Spectrum (13.2008.2438), Spectrum-2 (29.2008.2438) and Spectrum-3
(30.2008.2438).

This update fixes the following issues:

- An issue where strictly-prioritized traffic gets a 9usec latency penalty
  on a congested port.
- Attempts to configure DSCP prioritization (QPDM register) on CPU
  port (local port 0) would result in FW crash.
- An issue in sampling traffic to the CPU due to incorrect trap
  prioritization.
- An issue in bulk-reading flow counters.
- Several issues related to FW upgrade and in-service FW upgrade.
- Incomplete clearing of activity bits in ECMP containers with a very high
  number of individual ECMP entries (100K).
- A crash during router deinit.

for Spectrum (13.2008.2406), Spectrum-2 (29.2008.2406) and Spectrum-3
(30.2008.2406).

This release contains the following fixes and improvements:

- MIRROR_SAMPLER_ACTION.mirror_probability_rate inverted.
- When adjacency is replaced-if-inactive (RATR.opcode=3), bad parameter was
  reported when replacing an active entry.
- TC pool occupancy watermark not cleared after port splits.
- Per-TC counter of ECN-marked packets supported.
- When duplicating VXLAN packets for head-end replication, number of
  lookups was limited to 254, while Spectrum>=2 support 4K.
- Deadlock on port activation when 3 1x ports are active in a single port
  cluster on Spectrum-3.
- A storm of congestion threshold events generated on stably-congested
  traffic when a 200 Gbps port is flapped on Spectrum-3.
- Incorrect early scheduling parameters for 50G 2-way split on Spectrum-2.
- Timeouts when accessing certain CRspace addresses.
- Enable sampling trapped packets.

for Spectrum (13.2008.2304), Spectrum-2 (29.2008.2304) and Spectrum-3
(30.2008.2304).

This release fixes the following issues (among others):

- Rx pause packet reaction latency on Spectrum-3
- Certain high-numbered flow counters would not work on Spectrum-2.
- FW freeze on Spectrum-1 when under heavy PTP traffic load.
- Mirroring traffic to the CPU on Spectrum-2.
- Shared headroom would not be exhausted before drops started occurring.
- Per-priority Rx discard counters were not always cleared.
- 400-Gbps ports with PFC enabled kept sending pause frames without buffer
  pressure.
- Several issues in flow control and traffic admittance, and FW freeze
  after an on-the-fly shared buffer reconfiguration.
- A number of issues in forwarding line speed traffic to partially split
  8x ports on Spectrum-3.
- A number of issues related to in-service FW upgrade (ISSU / ISFU).
- Port shaper influenced ingress rate when PFC was enabled.
- FW freeze after a port was set admin down when unrelated ports were
  congested.

And includes the following new feature:

- Improvements to counter read performance

Add latest verified version of Mellanox Spectrum-family switch firmware,
for Spectrum (13.2008.2018), Spectrum-2 (29.2008.2018) and Spectrum-3
(30.2008.2018).

This release fixes the following issues (among others):

- Prioritization of trapped control traffic on Spectrum-2 and Spectrum-3.
- Several edge cases where the FW could get stuck on Spectrum-2 and
  Spectrum-3.
- FW flash issues on Spectrum-3
- Apparent resource exhaustion on Spectrum-3 due to wrong fencing.
- When trapping dropped packets from several TCs, they would only get
  reported under one TC.
- Incorrect rejection of RIF counters with indices over 16 bits.
- An issue where port split might fail after port saw heavy traffic.
- Certain large policer CIR caused effective zero CIR.
- A race that would cause drops due to lack of buffer space.

And includes the following new features:

- Support for shared port headroom
- A new trap for L2 IPv6 DHCP traffic
- On Spectrum-2 and Spectrum-3, support ACL actions that perform ALU
  operations between packet fields, immediate values and general-purpose
  registers
- Early support for 8-way port split on Spectrum-3
