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 5-1and described in the following paragraphs.

Table 5-1. Ql2x00ip.sys Configuration Parameters

Parameter	Minimum	Maximum	Recommended
			Default
MTU Size	92	65280	8192
Buffer Count	8	128	32
Buffer Size	512	65536	4096
Header Split Size	24	Buffer size –1	0a
Adapter Node Name	—	—	—

Table Notes

aA value of 0 indicates that the headers and data are not split.

■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.
