Using network_cli connection method on a illumos control node fails with termios.error: (22, 'Invalid argument')

SUMMARY

network_cli fails on illumos/SunOS/Solaris control nodes because termios tries to operate on the parent pty. When I try to run any ansible module from my illumos (SunOS) control node using the network_cli connection method, I get the following error:

The full traceback is: Traceback (most recent call last): File "/export/home/olbohlen/.local/lib/python3.9/site-packages/ansible/executor/task_executor.py", line 1155, in start_connection termios.tcsetattr(master, termios.TCSANOW, new) termios.error: (22, 'Invalid argument')

During handling of the above exception, another exception occurred:

The reason is described also in https://github.com/amoffat/sh/issues/143, you cannot call termios.tcsetattr() on the master side of the pty pair on Unix98 systems like illumos, Solaris, HP-UX, etc...

Unfortunately my python knowledge is way too bad to fix the issue by myself.

STEPS TO REPRODUCE

It is enough to try to run the ping module, even this will fail.

ansible -m ping bifroest.mgmt.home.eenfach.de

EXPECTED RESULTS

I expected to get the typical "ping": "pong" reply back

ACTUAL RESULTS
