1. Overview
Example:
#> ethtool -i eth2
driver: mlx4_en (MT_0BD0110004)
- version: 1.5.1 (March 2010)
- firmware-version: 2.7.0
+ version: 1.5.2 (March 2010)

- To query stateless offload status run:
- To modify rings size run:
#> ethtool -G eth<x> [rx <N>] [tx <N>]
-- To view card's vpd run:
- #> ethtool -e eth<x>
-
-- To modify card's vpd run:
- #> ethtool -E eth<x>
-
- To obtain additional device statistics, run:
#> ethtool -S eth<x>
Values of all parameters can be observed in /sys/module/mlx4_en/parameters/.
-3. Known Issues
-===============
-- For RedHat EL4, adding and removing multiple vlan interfaces over the network
- interface created by the mlx4_en driver may lead to printing the following:
- "kernel: unregister_netdevice: waiting for eth<x.y> to become free. Usage count ="
-
-4. Troubleshooting
-==================
-Problem: I restarted the driver and received the following error message:
- mlx4_core 0000:13:00.0: PCI device did not come back after reset, aborting.
- mlx4_core 0000:13:00.0: Failed to reset HCA, aborting.
-
-Suggestion: This error appears if you have burnt new firmware to the adapter
- card but have not rebooted the machine yet. Reboot the machine to allow the
- new firmware to take effect.
