Add back HW-GRO to the reported features. As the current implementation of HW-GRO uses KSMs with a specific fixed buffer size (256B) to map its headers buffer, we reported the feature only if the NIC is supporting KSM and the minimum value for buffer size is below the requested one. iperf3 bandwidth comparison: +---------+--------+--------+-----------+ | streams | SW GRO | HW GRO | Unit | |---------+--------+--------+-----------| | 1 | 36 | 42 | Gbits/sec | | 4 | 34 | 39 | Gbits/sec | | 8 | 31 | 35 | Gbits/sec | +---------+--------+--------+-----------+ A downstream patch will add skb fragment coalescing which will improve performance considerably.
