How to enable rx-gro-hw on ConnectX7

I’ve installed the latest Linux 6.11 kernel, which is supposed to support HW GRO on the ConnectX7 cards, but I’m still not able to enable it.

Are all ConnectX-7 cards supported, or just certain versions?

Here is the patch set I’m using: [PATCH net-next V2 00/14] net/mlx5e: SHAMPO, Enable HW GRO once more - Tariq Toukan

Here is info on my NIC (from mlxconfig):

Device type: ConnectX7
Name: MCX713106AS-VEA_Ax
Description: NVIDIA ConnectX-7 HHHL Adapter Card; 200GbE; Dual-port QSFP112; PCIe 5.0 x16; Crypto Disabled; Secure Boot Enabled

But ethtool still reports:
rx-gro-hw: off [fixed]

Hello,

Please make sure that you are using the latest LTS versions in both NIC Firmware and MLNX_OFED Driver.
You can find the Firmware .bin files here: Firmware for ConnectX®-7 InfiniBand | NVIDIA
And the MLNX_OFED driver and manual here: Linux InfiniBand Drivers

Once the latest versions are installed, please power-cycle the host, and see if the ethtool still shows rx-gro-hw: off [fixed].
If “Fixed” is still displayed, it means that the NIC model does not support enabling rx-gro-hw.

If you still encounter any issues after upgrading, please open a case with enterprisesupport@nvidia.com and it will be handled according to entitlement.

Thanks
