      Enet LLD memory footprint is ~10MB if using its default lwIP configuration. The main contributor to the footprint is the Ethernet packet memory.

      Multiple profile configurations should be provided to address specific use-cases like:

      1. 1. Minimal memory requirements focused on low-bandwidth transmission with or without lwip stack. Even single digit Rx/Tx buffer could potentially suffice here.
      2. 2. Nominal configuration (SDK's default configuration) that strikes a balance between performance, features and memory requirement. Recommended 64-128 Rx buffers and 32 Tx buffers, nominal size for TCP/UDP socket buffers.
      3. 3. Performance profile: Tight bound on memory requirements that gets us close to max performance entitlement. Increasing memory further would only yield diminished returns. Performance/data sheet numbers must be generated against this configuration.
