QL2x00IP NDIS Driver and IP Address Configuration
You must configure the IP address and modify the driver parameters during the
initial configuration as specified in
section 5.5.1 . You can also modify these later as
appropriate using the following procedures.
5.5.3.1
Driver Configuration
The QL2x00IP NDIS driver provides configuration parameters. The driver
configuration parameters are listed in
table 5-1 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.
■ Buffer Size. This parameter specifies the size of each receive buffer. The
buffer size multiplied by the number of buffers must be greater than or equal
to the MTU size. Incoming packets cannot be broken into more than
23 buffers. Therefore, the buffer size multiplied by 23 must be at least as
large as the MTU size. QLogic recommends a default value of 4096.
