The only way to tell whether or not it is supported by a given driver is to query the PCI vendor:device ID. Once you know these, you can query your system to see if the device is supported by any of your installed kernels: grep -i VendorID /lib/modules/*/modules.alias | grep -i DeviceID > I did not see a package that was obviously for that chipset in elrepo. > > Has that driver been backported into the RHEL/CentOS 7 kernel, and if > not, is it in elrepo? > > Worst case scenario I suppose it may be possible to port the driver like > many of the elrepo drivers have been, but not sure I want to buy > hardware based on a "may be possible" > > Thanks for any comments. >
