Caveats
Currently, 128 Mbyte of PCI memory space is used for this device/function.
Jumbo frames of maximum size 8000 are supported.
The current version of the Windows Win2k3 OS does not support MSI in the network
drivers (NDIS 5.1) and as a result MSI is not used by the Intelligent NIC driver.
However, hardware support is provided for NDIS versions 5.2 and 6.0.
6.4.1
MSI Interrupts for Linux
The Linux OS version supports MSI, and is used by the Intelligent NIC driver (if available).
On the Linux host, type
cat /proc/interrupts
to check that PCI-MSI is enabled for the
Ethernet interface
Determine if the installed Linux kernel has the MSI configuration option enabled
(earlier versions of the kernel may require an MSI patch).
Type
make
menuconfig
from the directory
/usr/src/kernels/<kernel version>
and
verify that MSI configuration option is supported/enabled.
6.4.2
PCI-Express Slot
The NetXen reference card can be located on the PCI-Express bus using the following
Linux command.
NetXen device ID = 4040
$ lspci | grep -i 4040
