Dear Etherlab users,
I am developing a software using Etherlab master patchset 20190904 for recent
kernels.
My environment is Linux Debian 9.5 with 4.9.0-8-amd64 kernel. I am using a
add-in network card, Kernel driver in use is ec_e100e.
I connect only one slave to the master.
I noticed strange behaviours when I unplug and reconnect network cable. First
times everythings is OK, I can see state link jump from up to down and down to
up, communication resumes.
But sometimes my software doesn't respond neither ethercat tools. Communication
is break down, command etherlab master doesn't work too.
I must reboot computer to make it works again.
As advised in the patch documentation, I add a rule with the following content
: ACTION=="add",KERNEL=="mei0",ATTR{../../power/control}="on" but that didn't
solve the problem.
I didn't notice something wrong in dmesg log below.
