Vendor driver vs Kernel, which one gets priority?

[Do Hak Yong]

Hello kernel experts,

I have a few questions about the priority of kernel drivers and third party
drivers.

If I install a third party vendor driver, which has the same module name as
kernel provides, for example, Qlogic driver has the same module name as
third party driver(qla2xxx).

The questions are:

Q1. Which driver has higher priority and which driver will be used? will
there any be problems?

Q2. How to control which driver the os will use?

Q3. What if the updated kernel installed and provied higher driver version
than third party? Which one will be used then?


I think third party drivers have more precedence that kernel drivers refer
to below Red Hat KB, but I'm not sure which one will be used when the
kernel has updated.

Your advice will be much appriciated.

Thank you
