No, as I mentioned in my original report, r295946 does NOT fix the problem.
11-CURRENT crashes too.

You can simulate the failure by changing the driver:

Index: if_ixl.c
--- if_ixl.c    (revision 297415)
+++ if_ixl.c    (working copy)
@@ -550,7 +550,7 @@
        /* Establish a clean starting point */
        error = i40e_pf_reset(hw);
-       if (error) {
+       if (1 || error) {
                device_printf(dev,"PF reset failure %x\n", error);
                error = EIO;
                goto err_out;

and then rebuilding and booting the kernel on a machine with an ixl interface.
