On node1 and node2, ifconfig ql0 mtu 4000, then ping link-local address from node1 to node2. Some glue in the driver's source code: ``` case SIOCSIFMTU: QL_DPRINT4(ha, "SIOCSIFMTU (0x%lx)\n", cmd); if (ifr->ifr_mtu > QLNX_MAX_MTU) { ret =3D EINVAL; } else { QLNX_LOCK(ha); ifp->if_mtu =3D ifr->ifr_mtu; ha->max_frame_size =3D ifp->if_mtu + ETHER_HDR_LEN + ETHER_CRC_LEN; if (ifp->if_drv_flags & IFF_DRV_RUNNING) { qlnx_init_locked(ha); } QLNX_UNLOCK(ha); } break; ``` --=20 You are receiving this mail because: You are the assignee for the bug.=
