usrsock_server: fix issues with usrsock_rpmsg_sendto_handler#9261
Merged
Conversation
If the current poll setup only has POLLIN, adding POLLOUT does not cause the protocol stack to refocus on flags such as TCP_ACK or UDP_POLL, the user is not notified when flags for POLLOUT relationships appear and vice versa, so we have to call poll_setup again.
