ixgbe, xsk: clean up the resources in ixgbe_xsk_pool_enable error path
In ixgbe_xsk_pool_enable(), if ixgbe_xsk_wakeup() fails, We should restore the previous state and clean up the resources. Add the missing clear af_xdp_zc_qps and unmap dma to fix this bug. Fixes: d49e286d354e ("ixgbe: add tracking of AF_XDP zero-copy state for each queue pair") Fixes: 4a9b32f30f80 ("ixgbe: fix potential RX buffer starvation for AF_XDP") Signed-off-by: Wang Hai <[email protected]> Acked-by: Magnus Karlsson <[email protected]> Tested-by: Sandeep Penigalapati <[email protected]> Signed-off-by: Tony Nguyen <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
