QL2x00IP NDIS Driver Configuration
You must configure the IP address and modify the driver parameters during the
initial installation (see section 6.5.1). You can also modify these later as appropriate
using the following procedures.
The QL2x00IP NDIS driver provides drive configuration parameters. The drive
configuration parameters are listed in table 6-1 and described in the following
paragraphs.
MTU Size. This parameter specifies the maximum transfer or packet size
that the host system sends or receives. All QLA22xx/QLA23xx HBAs on the
same network must have the same MTU size value. QLogic recommends
a default value of 8192.
Buffer Count. This parameter specifies the number of receive buffers that
the QL2x00IP driver allocates during initialization. The number of buffers
multiplied by the buffer size must be greater than or equal to the MTU size.
QLogic recommends a default value of 32.
