Device ID comparison in igc_is_device_id_i226 is performed before
the ID is set, resulting in always failing check on init.
Before the patch:
* L1.2 is not disabled on init
* L1.2 is properly disabled after suspend-resume cycle
With the patch:
* L1.2 is properly disabled both on init and after suspend-resume
How to test:
Connect to the 1G link with 300+ mbit/s Internet speed, and run
the download speed test, such as:
curl -o /dev/null http://speedtest.selectel.ru/1GB
Without L1.2 disabled, the speed would be no more than ~200 mbit/s.
With L1.2 disabled, the speed would reach 1 gbit/s.
Note: it's required that the latency between your host and the remote
be around 3-5 ms, the test inside LAN (<1 ms latency) won't trigger the
issue.
