Impressive, it needed just a small addition to sys/conf/files to make
the linker happy :-)
I also recomplied vale-ctl, but I get the following error when trying to
add em0 (lagg-unrelated):
389.083433 [ 835] netmap_obj_malloc netmap_ring request size
65792 too large
389.091593 [1693] netmap_mem2_rings_create Cannot allocate RX_ring
Adding lagg still results in a panci, but with your latest
"return()"-patch, it's different:
0xffffffff8042aefb is in freebsd_generic_rx_handler
(/usr/local/share/deploy-tools/RELENG_11/src/sys/dev/netmap/netmap_freebsd.c:276).
271 struct netmap_generic_adapter *gna =
272 (struct netmap_generic_adapter *)NA(ifp);
273 int stolen = generic_rx_handler(ifp, m);
274
275 if (!stolen) {
276 gna->save_if_input(ifp, m);
277 }
278 }

Any hints how I can get adding em0 (lagg and vlan-less) via vale-ctl
again? (netmap_obj_malloc netmap_ring request size 65792 too large)
Thanks,
