Ethernet wqe_too_small Mode

Added a new counter per vPort that counts the number of packets that reached the Ethernet RQ but cannot fit into the WQE due to their large size. Additionally, we added the option to control if such packet will cause “CQE with Error” or “CQE_MOCK”.

Counters

Added support for the cq_overrun counter. The counter represents the number of times CQs enter an error state due to overflow that occur when the device tries to post a CQE into a full CQ buffer.

Pause Frames from VFs

[Beta] Enabled the capability to allow Virtual Functions to send Pause Frames packets.

Auto-Sensing

Enabled 10/25GbE auto-sensing with 3rd party when using 10/25GbE optical cables.
