Driver Parameters Several optional parameters can be supplied as a command line argument to the vmkload_mod command. These parameters can also be set via the esxcfg-module command. See the man page for more information. int_mode The optional parameter int_mode is used to force using an interrupt mode other than MSI-X. By default, the driver will try to enable MSI-X if it is supported by the kernel. If MSI-X is not attainable, then the driver will try to enable MSI if it is supported by the kernel. If MSI is not attainable, then the driver will use the legacy INTx mode. Set the int_mode parameter to 1 as shown below to force using the legacy INTx mode on all NetXtreme II network adapters in the system. vmkload_mod bnx2x int_mode=1 Set the int_mode parameter to 2 as shown below to force using MSI mode on all NetXtreme II network adapters in the system. vmkload_mod bnx2x int_mode=2 disable_tpa The optional parameter disable_tpa can be used to disable the Transparent Packet Aggregation (TPA) feature. By default, the driver will aggregate TCP packets, but if you would like to disable this advanced feature, it can be done. Set the disable_tpa parameter to 1 as shown below to disable the TPA feature on all NetXtreme II network adapters in the system. file:///T|/htdocs/NETWORK/BroadCom/71921/NetXtremeII/en/vmware.htm[9/26/2012 3:28:54 PM]
