A Network driver parameters rx Receive on or off tx Transmit on or off Managing Linux driver configuration with module parameter Either the driver configuration parameter values can be loaded with the driver or can be set in /etc/modprobe.conf before loading the driver. Following are examples of using modprobe to change network driver configuration: • This example, sets the Linux logging level to debugging mode and loads the driver with the parameter value. modprobe bna bnad_log_level=7 • This example sets the Linux logging level to debugging mode. Add the entry in /etc/modprobe.conf, then load the driver. options bna bnad_log_level=7 • This example enables or disables MSI-X and loads the driver with the parameter value. modprobe bna bnad_msix=[0|1] • This example enables or disables MSI-X. Add the entry in /etc/modprobe.conf, then load the driver. options bna bnad_msix=[0|1] NOTE MSI-X is enabled in the network driver by default, and must remain enabled for NetQueue to function. Enabling NetQueue in VMware system also enables MSI-X in the system. If enabling NetQueue, make sure that bnad_msix=0 is not listed in VMware module parameters because that would disable NetQueue. Managing Linux driver configuration with module ifconfig Following are examples of using ifconfig to change network driver configuration. • This example, sets the locally administered MAC address. ifconfig ethX hw ether [addr] where: ethx Adapter position in server. For example, eth0 is the first Ethernet interface found in the system, eth1 is the second, eth2 is the third, and so on. • This example, sets the Jumbo Packet (MTU) size. ifconfig ethx mtu where: ethX MTU size Adapter position in server. For example, eth0 is the first Ethernet interface found in the system, eth1 is the second, eth2 is the third, and so on. MTU size (1500-9000 kb) 218 Brocade Adapters Installation and Reference Manual 53-1002144-01
