or to persist the settings across reboots with the command
esxcfg-module -s multi_mode=0 bnx2x
Reboot the machine for the settings to take place.
MultiQueue/NetQueue
The optional parameter
num_queues
may be used to set the number of Rx and
Tx queues when
multi_mode
is set to 1 and interrupt mode is MSI-X. If interrupt
mode is different than MSI-X (see
int_mode
parameter), the number of Rx and Tx
queues will be set to 1, discarding the value of this parameter.
If you would like the use of more then 1 queue, force the number of NetQueues to
use with the following command:
esxcfg-module -s "multi_mode=1 num_queues=<num of queues>" bnx2x
Otherwise, allow the bnx2x driver to select the number of NetQueues to use with
the following command:
esxcfg-module -s "multi_mode=1 num_queues=0" bnx2x
The optimal number is to have the number of NetQueues match the number of
CPUs on the machine.
