The UMEM state refactor made __send_pkts() use xsk->umem for Tx
address generation. At the same time, the shared-UMEM Tx setup copies the
Rx UMEM state into a Tx-local state object and resets base_addr and
next_buffer before configuring the Tx socket.

Passing that Tx-local object to xsk_configure() makes xsk->umem point to
the zero-based Tx allocator state. This breaks the BIDIRECTIONAL test once
the roles are switched: the same socket is then used for Rx validation, but
received descriptors from the other logical UMEM half are checked against
base_addr == 0. With the new UMEM bounds check, a valid address such as
base_addr + XDP_PACKET_HEADROOM is rejected as being outside the UMEM
window.

You are awesome, thank you!
