When page size is 64K, RX buffer is currently not reused when the page_offset is moved to last buffer. This patch adds checking to decide whether the buffer page can be reused when last_offset is moved beyond last offset. If the driver is the only user of page when page_offset is moved to beyond last offset, then buffer can be reused and page_offset is set to zero.

2019-05-07net: hns3: fix error handling for desc fillingYunsheng Lin
When desc filling fails in hns3_nic_net_xmit, it will call hns3_clear_desc to unmap the dma mapping. But currently the ring->next_to_use points to the desc where the desc filling or dma mapping return error, which means the desc that ring->next_to_use points to has not done the dma mapping, the desc that need unmapping is before the ring->next_to_use. This patch fixes it by calling ring_ptr_move_bw(next_to_use) before doing unmapping operation, and set desc_cb->dma to zero to avoid freeing it again when unloading. Also, when filling skb head or frag fails, both need to unmap all the way back to next_to_use_head, so remove one desc filling error handling.

When filling len and checksum info to description, there is some similar checking or calculation. So this patch adds hns3_set_l2l3l4 to fill the inner(/normal) header's len and checksum info. If it is a encapsulation skb, it calls hns3_set_outer_l2l3l4 to handle the outer header's len and checksum info, in order to avoid some similar checking or calculation.

Currently the tunnel packet type is decided by the rx.l234_info, which may cause RX checksum handling error.

2019-05-07net: dsa: lantiq: Add VLAN aware bridge offloadingHauke Mehrtens
The VLAN aware bridge offloading is similar to the VLAN unaware offloading, this makes it possible to offload the VLAN bridge functionalities. The hardware supports up to 64 VLAN bridge entries, we already use one entry for each LAN port to prevent forwarding of packets between the ports when the ports are not in a bridge, so in the end we have 57 possible VLANs. The VLAN filtering is currently only active when the ports are in a bridge, VLAN filtering for ports not in a bridge is not implemented. It is currently not possible to change between VLAN filtering and not filtering while the port is already in a bridge, this would make the driver more complicated. The VLANs are only defined on bridge entries, so we will not add anything into the hardware when the port joins a bridge if it is doing VLAN filtering, but only when an allowed VLAN is added.

2019-05-07net: dsa: lantiq: Add VLAN unaware bridge offloadingHauke Mehrtens
This allows to offload bridges with DSA to the switch hardware and do the packet forwarding in hardware. This implements generic functions to access the switch hardware tables, which are used to control many features of the switch. This patch activates the MAC learning by removing the MAC address table lock, to prevent uncontrolled forwarding of packets between all the LAN ports, they are added into individual bridge tables entries with individual flow ids and the switch will do the MAC learning for each port separately before they are added to a real bridge. Each bridge consist of an entry in the active VLAN table and the VLAN mapping table, table entries with the same index are matching. In the VLAN unaware mode we configure everything with VLAN ID 0, but we use different flow IDs, the switch should handle all VLANs as normal payload and ignore them. When the hardware looks for the port of the destination MAC address it only takes the entries which have the same flow ID of the ingress packet. The bridges are configured with 64 possible entries with these information: Table Index, 0...63 VLAN ID, 0...4095: VLAN ID 0 is untagged flow ID, 0..63: Same flow IDs share entries in MAC learning table port map, one bit for each port number tagged port map, one bit for each port number Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

In addition, this optimization makes kernel_fpu_begin() cheaper by requiring registers saving only on the first invocation and skipping that in following ones.

2019-05-07vfio/mdev: Fix aborting mdev child device removal if one failsParav Pandit
device_for_each_child() stops executing callback function for remaining child devices, if callback hits an error. Each child mdev device is independent of each other. While unregistering parent device, mdev core must remove all child mdev devices. Therefore, mdev_device_remove_cb() always returns success so that device_for_each_child doesn't abort if one child removal hits error. While at it, improve remove and unregister functions for below simplicity. There isn't need to pass forced flag pointer during mdev parent removal which invokes mdev_device_remove(). So simplify the flow. mdev_device_remove() is called from two paths. 1. mdev_unregister_driver() mdev_device_remove_cb() mdev_device_remove() 2. remove_store() mdev_device_remove() Fixes: 7b96953bc640 ("vfio: Mediated device Core driver") Reviewed-by: Maxim Levitsky <mlevitsk@redhat.com> Signed-off-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
