Created: May 29, 2014    Updated: Dec 19, 2017
Resolved Date: Sep 14, 2014
Previous ID: LIN4-31415
Found In Version: 5.0
Severity: Standard
Applicable for: Wind River Linux 5
Component/s: Userspace

Description

Since upgrade to RCPL 23, which contains a fix for LIN4-13368, ethtool no longer works as expected with the uprev'ed ixgbe driver.

Steps to Reproduce

Using an x86-64 target, glibc_cgl rootfs.

# ethtool -h|grep -i versi
ethtool version 2.6.33-pre1
# ethtool -i eth2
driver: ixgbe
version: 3.17.3
firmware-version: 0x80000344
bus-info: 0000:02:00.0
# ethtool -d eth2
Cannot dump registers: Success

Customer compiled a more recent version of ethtool and found it to work correctly:

# ./ethtool --version
ethtool version 3.13
# ./ethtool -i eth2  
driver: ixgbe
version: 3.17.3
firmware-version: 0x80000344
bus-info: 0000:02:00.0
