[ Upstream commit 11fc79fc9f2e395aa39fa5baccae62767c5d8280 ]
When calling xsk_socket__create_shared(), the logic at line 1097 marks a
boolean flag true within the xsk_umem structure to track setup progress
in order to support multiple calls to the function. However, instead of
marking umem->tx_ring_setup_done, the code incorrectly sets
umem->rx_ring_setup_done. This leads to improper behaviour when
creating and destroying xsk and umem structures.
Multiple calls to this function is documented as supported.
Fixes: ca7a83e2487a ("libbpf: Only create rx and tx XDP rings when necessary")
