      tcp: fix rate_app_limited to default to 1 · 300b655d
      David Morley authored
      The initial default value of 0 for tp->rate_app_limited was incorrect,
      since a flow is indeed application-limited until it first sends
      data. Fixing the default to be 1 is generally correct but also
      specifically will help user-space applications avoid using the initial
      tcpi_delivery_rate value of 0 that persists until the connection has
      some non-zero bandwidth sample.

      net: stmmac: enable all safety features by default · fdfc76a1
      Andrew Halaney authored
      In the original implementation of dwmac5
      commit 8bf993a5 ("net: stmmac: Add support for DWMAC5 and implement Safety Features")
      all safety features were enabled by default.
      
      Later it seems some implementations didn't have support for all the
      features, so in
      commit 5ac712dc ("net: stmmac: enable platform specific safety features")
      the safety_feat_cfg structure was added to the callback and defined for
      some platforms to selectively enable these safety features.
      
      The problem is that only certain platforms were given that software
      support. If the automotive safety package bit is set in the hardware
      features register the safety feature callback is called for the platform,
      and for platforms that didn't get a safety_feat_cfg defined this results
      in the following NULL pointer dereference:

      Go back to the original behavior, if the automotive safety package
      is found to be supported in hardware enable all the features unless
      safety_feat_cfg is passed in saying this particular platform only
      supports a subset of the features.

      Nithin Dabilpuram authored
      CN10K CPT coprocessor includes a component named RXC which
      is responsible for reassembly of inner IP packets. RXC has
      the feature to evict oldest entries based on age/threshold.
      The age/threshold is being set to minimum values to evict
      all entries at the time of teardown.
      This patch adds code to restore timeout and threshold config
      after teardown sequence is complete as it is global config.

      On OcteonTX2 platform CPT instruction enqueue is only
      possible via LMTST operations.
      The existing FLR sequence mentioned in HRM requires
      a dummy LMTST to CPT but LMTST can't be submitted from
      AF driver. So, HW team provided a new sequence to avoid
      dummy LMTST. This patch adds code for the same.
