This is a subsytem for anything related to Earth Computing link protocols (ECLP). Models of protocols should be checked directly into driver-master unless specific to particular code in a lower-level branch.

WARNING

For the time being leave the old driver in initramfs - i.e. the Atsushi driver.
Development is done by blacklisting the initramfs driver and dynamically loading driver(s).

to avoid loading old demo driver

$ echo "blacklist e1000e" >> /etc/modprobe.d/e1000e.conf

or edit (using sudo) /etc/modprobe.d/e1000e.conf to uncomment "blacklist e1000e".

then:

$ sudo depmod -ae && sudo update-initramfs -u

Then reboot. TO RETURN TO OLD-DEMO BEHAVIOR, RECOMMENT THE LINE IN /etc/modprobe.d/e1000e.conf

on startup, dynamically load kernel modules

$ cd driver
driver$ sudo insmod e1000e/e1000e-3.3.4/src/e1000e.ko
driver$ sudo insmod ecnl/src/ecnl_device.ko

testing hints

$ egrep 'ADAPT|ECNL|ENTL|e1000' /var/log/syslog ; tail -f /var/log/syslog | egrep 'ADAPT|ECNL|ENTL|e1000'

Find the modules
