The current codebase calls the function no matter net device has XDP programs or not. So the finalize function is being called everytime when RX bottom-half in progress. It needs a few machine instructions for nothing in the case that XDP programs are not attached at all. Lets it call the function on a condition that if xdp_status variable has not zero value. That means XDP programs are attached to the net device and it should be finalized based on the variable. The following instructions show that it's better than calling the function unconditionally. 0.31 │6b8: ldr w0, [sp, torvalds#196] │ ┌──cbz w0, 6cc │ │ mov x1, x0 │ │ mov x0, x27 │ │→ bl stmmac_finalize_xdp_rx │6cc:└─→ldr x1, [sp, torvalds#176] with 'if (xdp_status)' statement, jump to '6cc' label if xdp_status has zero value.
