Subject: [PATCH v3 net 0/4] Fix passing 0 to ERR_PTR in intel ether drivers

Fixing sparse error in xdp run code by introducing new variable xdp_res
instead of overloading this into the skb pointer as i40e drivers done
in commit 12738ac4754e ("i40e: Fix sparse errors in i40e_txrx.c") and

    kernel test robot
v2: Fix this as i40e drivers done instead of return NULL in xdp run code

  igb: Fix passing 0 to ERR_PTR in igb_run_xdp()
  ixgbe: Fix passing 0 to ERR_PTR in ixgbe_run_xdp()
  ixgbevf: Fix passing 0 to ERR_PTR in ixgbevf_run_xdp()
