Description
As originally reported in #4504 a port could be open first with ReadShared and then with ReadExclusive the internal state of the port was incorrectly changed. This meant that the same port could be used at the same time for unicast and multicast.
This PR fixes #4634 by checking incompatibilities inside
lock_read_exlcusive
/lock_read_shared
methods of the Port class.@Mergifyio backport 2.13.x 2.10.x 2.6.x
