2. If the driver is provided separately, it must be extracted and compiled for the kernel running on the x86 host and installed.
Example commands are provided below:
NOTE:
It is assumed that the delivered L2 source code is in the tarball
brcm-nxt-l2-drv.tar.gz
.
tar zxf brcm-nxt-l2-drv.tar.gz
cd git/main/Cumulus/drivers/linux/v3/
make
sudo make install
The driver name is
bnxt_en.ko
and the last command installs it in the system in the
/lib/modules/<kernel-
version>/updates/
directory.
3. Install the driver using the following command:
sudo modprobe bnxt_en
3.4.2 Assigning an IP Address to the First New Host Interface
After a
modprobe
or
insmod
of the
bnxt_en
driver, the new network interfaces show up on the x86 host. The number of
interfaces/PFs that show up on the x86 host and separately on the ARM side is Nitro firmware-dependent. An example for
x86 is shown below and the interfaces are
highlighted
.
NOTE:
The exact names may differ from system to system and depend on the OS being used and the physical slot where
the card is installed.
