The mvneta driver and hardware supports IPv6 offload, however it isn't enabled. Set the NETIF_F_IPV6_CSUM feature to inform the network layer that this driver can offload IPV6 TCP and UDP checksums. This change has been tested on an Armada 370 and the feature support confirmed with several device datasheets including the Armada XP and Armada 3700. Signed-off-by:

At the end of the do while loop the integer counter retries will always be zero and so the subsequent check to see if it is zero is always true and therefore redundant. Remove the redundant check and always return -EIO on this return path. Also unbreak the literal string in dev_err message to clean up a checkpatch warning.

Antoine Tenart says: ==================== net: mvpp2: optional PHYs and GoP link irq This series aims at making the driver work when no PHY is connected between a port and the physical layer and not described as a fixed-phy. This is useful for some usecases such as when a switch is connected directly to the serdes lanes. It can also be used for SFP ports on the 7k-db and 8k-db while waiting for the phylink support to land in (which should be part of another series). This series makes the phy optional in the PPv2 driver, and then adds the support for the GoP port link interrupt to handle link status changes on such ports. This was tested using the SFP ports on the 7k-db and 8k-db boards. Since v1: - Now use phy_interface_mode_is_rgmii() in the GoP link patch. - Added one cosmetic patch to take advantage of phy_interface_mode_is_rgmii() in the whole PPv2 driver. ==================== Signed-off-by: -

This patch adds the GoP link interrupt support for when a port isn't connected to a PHY. Because of this the phylib callback is never called and the link status management isn't done. This patch use the GoP link interrupt in such cases to still have a minimal link management. Without this patch ports not connected to a PHY cannot work. Signed-off-by:

Antoine Tenart authored
There is not necessarily a PHY between the GoP and the physical port. However, the driver currently makes the "phy" property mandatory, contrary to what is stated in the device tree bindings. This patch makes the PHY optional, and aligns the PPv2 driver on its device tree documentation. However if a PHY is provided, the GoP link interrupt won't be used. With this patch switches directly connected to the serdes lanes and SFP ports on the Armada 8040-db and Armada 7040-db can be used if the link interrupt is described in the device tree.

Ido Schimmel authored
When the abort mechanism is invoked a default route directing packets to the CPU is programmed in all the virtual routers currently in use. This can result in packet loss in case a new VRF is configured. Upon abort, program the default route in all virtual routers, whether they are in use or not. The patch is directed at net-next since post-abort fixes aren't critical and packet loss due to a missing default route will be insignificant compared to packet loss caused by the CPU port policer.

I relied on the fact that anycast routes use the loopback device as their nexthop device to trap packets hitting them to the CPU. After commit 4832c30d ("net: ipv6: put host and anycast routes on device with address") this is no longer the case and such routes are programmed with a forward action (note the 'offload' flag): anycast cafe:: dev enp3s0np7 proto kernel metric 0 offload pref medium This will prevent the router from locally receiving packets destined to the Subnet-Router anycast address. Fix this by specifically programming anycast routes with action trap, which results in the following output: anycast cafe:: dev enp3s0np7 proto kernel metric 0 pref medium Fixes: 4832c30d ("net: ipv6: put host and anycast routes on device with address") Signed-off-by:

Inline the lru map lookup to save the cost in making calls to bpf_map_lookup_elem() and htab_lru_map_lookup_elem(). Different LRU hash size is tested. The benefit diminishes when the cache miss starts to dominate in the bigger LRU hash. Considering the change is simple, it is still worth to optimize.

Create a new case to test the LRU lookup performance. At the beginning, the LRU map is fully loaded (i.e. the number of keys is equal to map->max_entries). The lookup is done through key 0 to num_map_entries and then repeats from 0 again. This patch also creates an anonymous struct to properly name the test params in stress_lru_hmap_alloc() in map_perf_test_kern.c. Signed-off-by:
