Research direction

Start at Flush() and trace the netlink receive path associated with the reported recvmsg error. Reproduce the failure by combining messages whose payload crosses the netlink buffer size, then determine the expected application-facing behavior or API and document it with a regression test.

Written by the indexing model from the issue text.

Description

I observed that when we combine multiple messages and call Flush, the Flush may fail (with error "Receive: netlink receive: recvmsg: no buffer space available") if the message payload crosses netlink buffer size.
Currently Flush() doesn't handle it? is application supposed to handle it? is there any API exposed from which application can know if the netlink message size is exceeded?
