QL2200IP NDIS Driver Configuration

The QL2200IP NDIS driver provides optional configuration parameters. The

configuration parameters are listed in table 4-1 and described in the following

paragraphs.

❑ MTU Size. This parameter specifies the maximum transfer or packet size

that the host system will send or receive. All systems on the 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 QL2200IP driver allocates during initialization. The number of buffers

multiplied by the buffer size must be equal to or greater than 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 equal to or greater

than the MTU size. QLogic recommends a default value of 4096.

❑ Header Split Size. This parameter accounts for packets with split headers

and data. The parameter value specifies the number of bytes at the beginning

of an incoming packet that must be isolated in the first receive buffer. A

zero value indicates that the packet header and data are not split. QLogic

recommends a default value of 0.
