* net: hns3: Enable promisc mode when mac vlan table is fullJian Shen2018-10-124-12/+89
| | | | | | | | | | | | | | Currently, the driver does nothing when mac vlan table is full. In this case, the packet with new mac address will be dropped by hardware. This patch adds check for the result of sync mac address, and enable promisc mode when mac vlan table is full. Furtherly, disable vlan filter when enable promisc by user command.

* | mlxsw: spectrum: Add NVE packet trapsIdo Schimmel2018-10-112-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DECAP_ECN0 trap will be used to trap packets where the overlay packet is marked with Non-ECT, but the underlay packet is marked with either ECT(0), ECT(1) or CE. When trapped, such packets will be counted as errors by the VxLAN driver and thus provide better visibility. The NVE_ENCAP_ARP trap will be used to trap ARP packets undergoing NVE encapsulation. This is needed in order to support E-VPN ARP suppression, where the Linux bridge does not flood ARP packets through tunnel ports in case it can answer the ARP request itself. Note that all the packets trapped via these traps are marked with 'offload_fwd_mark', so as to not be re-flooded by the Linux bridge through the ASIC ports.
