Problem in loading nvme driver

[nikhith g.k]

Hi,

I am new to freebsd and using 10.4 operating system to build and load my
customized nvme driver.

After building the driver I am facing some issues in loading it.

Already kernel includes nvme.ko but it is not loaded.So I am trying load
my customized nvme driver dynamically  with the below command line .
Kldload -v ./nvme   and getting the below error.
Interface nvme.1 already present in the kld kernel.


Can you please give me information on how to load my customized driver
dynamically?

Thanks,
Nikhith
