Yewon Choi d7666bfd78 xsk: Skip polling event check for unbound socket ... [ Upstream commit e4d008d49a7135214e0ee70537405b6a069e3a3f ] In xsk_poll(), checking available events and setting mask bits should be executed only when a socket has been bound. Setting mask bits for unbound socket is meaningless. Currently, it checks events even when xsk_check_common() failed. To prevent this, we move goto location (skip_tx) after that checking.
