Driver Parameters
The following sections describe the parameters for these VMware ESXi drivers:
bnx2x Driver Parameters
Several optional bnx2x driver parameters can be supplied as a command line
argument to the
vmkload_mod
command. These parameters can also be set
with the
esxcfg-module
command. See the man page for more information.
int_mode
Use the optional parameter
int_mode
to force using an interrupt mode other
than MSI-X. By default, the driver tries to enable MSI-X if it is supported by the
kernel. If MSI-X is not attainable, the driver tries to enable MSI if it is supported by
the kernel. If MSI is not attainable, the driver uses the legacy INTx mode.
To force using the legacy INTx mode on all 8400/3400 Series network adapters in
the system, set the
int_mode
parameter to
1
as shown in the following:
vmkload_mod bnx2x int_mode=1
To force using MSI mode on all 8400/3400 Series network adapters in the system,
set the
int_mode
parameter to
2
as shown in the following:
vmkload_mod bnx2x int_mode=2
disable_tpa
Use the optional parameter
disable_tpa
to disable the transparent packet
aggregation (TPA) feature. By default, the driver aggregates TCP packets.
To disable the TPA feature on all 8400/3400 Series Adaptersnetwork adapters in
the system, set the
disable_tpa
parameter to
1
:
vmkload_mod bnx2x.ko disable_tpa=1
Use ethtool to disable TPA (LRO) for a specific network adapter.
