QL2200IP NDIS Driver Configuration
The QL2200IP NDIS driver provides optional configuration parameters. The
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 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.
