[Qemu-devel] [PATCH 01/12] slirp: remove QEMU_PACKED from structures with don't require it

[Philippe Mathieu-Daudé]

theses structures are not serialized and often store host pointers.

  slirp/ip_input.c:159:43: warning: taking address of packed member 'ip_link' 
of class or
        structure 'ipq' may result in an unaligned pointer value
        [-Waddress-of-packed-member]
                  for (l = slirp->ipq.ip_link.next; l != &slirp->ipq.ip_link;
                                                          ^~~~~~~~~~~~~~~~~~
