ethtool - utility for controlling network drivers and hardware

Introduction

ethtool is the standard Linux utility for controlling network drivers and hardware, particularly for wired Ethernet devices. It can be used to:

Get identification and diagnostic information

Get extended device statistics

Control speed, duplex, autonegotiation and flow control for Ethernet devices

Control checksum offload and other hardware offload features

Control DMA ring sizes and interrupt moderation

Control receive queue selection for multiqueue devices

Upgrade firmware in flash memory

Most features are dependent on support in the specific driver. See the manual page for full information.

cross compile ethtool

step 1: Download ethtool-3.6.tar.bz2 from http://www.kernel.org/pub/software/network/ethtool/
step 2: tar -jxvf ethtool-3.6.tar.bz2

step 3: cd ethtool-3.6, touch cross_configure.sh as follow:

MIPS_TOOLCHAIN_DIR=/opt/mips-4.4/bin

export CROSS_COMPILE="${MIPS_TOOLCHAIN_DIR}/mips-linux-gnu-"

export AR="${CROSS_COMPILE}ar"

export AS="${CROSS_COMPILE}as"

export LD="${CROSS_COMPILE}ld"

export NM="${CROSS_COMPILE}nm"

export CC="${CROSS_COMPILE}gcc -Os -pipe -O2 -mtune=mips32r2 -mabi=32 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -EL"

export FC="${CROSS_COMPILE}gfortran "

export RANLIB="${CROSS_COMPILE}ranlib"

export STRIP="${CROSS_COMPILE}strip"

export OBJCOPY="${CROSS_COMPILE}objcopy"

export CFLAGS="-Os -pipe -O2 -mtune=mips32r2 -mabi=32 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -EL"

export CXXFLAGS="-Os -pipe -O2 -mtune=mips32r2 -mabi=32 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -EL"

./configure --target=mipsel-linux --host=mipsel-linux

step 4: ./cross_configure.sh, make

step 5: cp ethtool-3.6/ethtool to target board.

step 6: use "./ethtool -S eth0" to watch network status.
