The cause is fairly obvious. e6000sw creates struct ifnets that don't have an ioctl handler, and that's triggering this crash. The following is probably the best fix, assuming that the ioctl-less e6000sw ifnet is intentional: diff --git a/sys/net/if.c b/sys/net/if.c index 9f44223af0dd..c3c27fbf678f 100644 --- a/sys/net/if.c +++ b/sys/net/if.c @@ -4871,6 +4871,9 @@ if_resolvemulti(if_t ifp, struct sockaddr **srcs, struct sockaddr *dst) int if_ioctl(if_t ifp, u_long cmd, void *data) { + if (ifp->if_ioctl == NULL) + return (EOPNOTSUPP); + return (ifp->if_ioctl(ifp, cmd, data)); } -- You are receiving this mail because: You are the assignee for the bug.
