Maciej Fijalkowski 53fc61be27 ice: xsk: do not use xdp_return_frame() on tx_buf->raw_buf ... Previously ice XDP xmit routine was changed in a way that it avoids xdp_buff->xdp_frame conversion as it is simply not needed for handling XDP_TX action and what is more it saves us CPU cycles. This routine is re-used on ZC driver to handle XDP_TX action. Although for XDP_TX on Rx ZC xdp_buff that comes from xsk_buff_pool is converted to xdp_frame, xdp_frame itself is not stored inside ice_tx_buf, we only store raw data pointer. Casting this pointer to xdp_frame and calling against it xdp_return_frame in ice_clean_xdp_tx_buf() results in undefined behavior. To fix this, simply call page_frag_free() on tx_buf->raw_buf. Later intention is to remove the buff->frame conversion in order to simplify the codebase and improve XDP_TX performance on ZC.
