Linux Driver Messages
To set the Linux driver message detail level, issue one of the following commands:
ethtool -s <interface> msglvl <value>
modprobe qede debug=<value>
Where
<value>
represents bits 0–15, which are standard Linux networking
values, and bits 16 and greater are driver-specific.
Statistics
To view detailed statistics and configuration information, use the ethtool utility. See
the ethtool man page for more information.
Importing a Public Key for Secure Boot
Linux drivers require that you import and enroll the QLogic public key to load the
drivers in a Secure Boot environment. Before you begin, ensure that your server
supports Secure Boot. This section provides two methods for importing and
enrolling the public key.
To import and enroll the QLogic public key:
1.
Download the public key from the following Web page:
http://ldriver.qlogic.com/Module-public-key/
2.
To install the public key, issue the following command:
#
mokutil --root-pw --import cert.der
Where the
--root-pw
option enables direct use of the root user.
3.
Reboot the system.
