* net: stmmac: dwc-qos: Split out ->probe() and ->remove()Thierry Reding2017-03-131-26/+98
| | | | | | | | | | | | | Split out the binding specific parts of ->probe() and ->remove() to enable the driver to support variants of the binding. This is useful in order to keep backwards-compatibility while making it easy for a sub- driver to deal only with the updated bindings rather than having to add compatibility quirks all over the place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While running a single stream UDPv6 test, we observed that amount of CPU spent in NET_RX softirq was much greater than UDPv4 for an equivalent receive rate. The test here was run on an ARM64 based Android system. On further analysis with perf, we found that UDPv6 was spending significant time in the statistics netfilter targets which did socket lookup per packet. These statistics rules perform a lookup when there is no socket associated with the skb. Since there are multiple instances of these rules based on UID, there will be equal number of lookups per skb. By introducing early demux for UDPv6, we avoid the redundant lookups. This also helped to improve the performance (800Mbps -> 870Mbps) on a CPU limited system in a single stream UDPv6 receive test with 1450 byte sized datagrams using iperf. v1->v2: Use IPv6 cookie to validate dst instead of 0 as suggested by Eric Signed-off-by: Subash Abhinov Kasiviswanathan <subashab@codeaurora.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original reason [1] for having hidden qdiscs (potential scalability issues in qdisc_match_from_root() with single linked list in case of large amount of qdiscs) has been invalidated by 59cc1f61f0 ("net: sched: convert qdisc linked list to hashtable"). This allows us for bringing more clarity and determinism into the dump by making default pfifo qdiscs visible. We're not turning this on by default though, at it was deemed [2] too intrusive / unnecessary change of default behavior towards userspace. Instead, TCA_DUMP_INVISIBLE netlink attribute is introduced, which allows applications to request complete qdisc hierarchy dump, including the ones that have always been implicit/invisible. Singleton noop_qdisc stays invisible, as teaching the whole infrastructure about singletons would require quite some surgery with very little gain (seeing no qdisc or seeing noop qdisc in the dump is probably setting the same user expectation).

Instead, bind the RIF to a VR according to the table where FIB lookup should be performed for packets received via the RIF.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A virtual router (VR) is an entity within the device to which routing tables and interfaces can be bound to. It can be used to implement VRFs. In the initial implementation we associated the VR with a specific protocol (e.g., IPv4) and an LPM tree. However, this isn't really accurate, as the same VR can be used for both IPv4 and IPv6 traffic, by binding a different LPM tree to a {VR, Proto} pair. This patch aims to restructure the VR code according to the above logic, so that VRs are more accurately represented by the driver's data structures. The main motivation behind this change is to prepare the driver for VRF offload.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When looking for a new LPM tree we should always consider all the unused trees. It doesn't matter if the new tree is required due to changes in currently used prefixes inside an existing routing table or because a route was inserted into an empty table. Both cases are functionally identical and therefore should be treated the same. When looking for a new LPM tree, consider all unused trees and don't reserve trees for specific cases.

| * | mlxsw: spectrum_router: Place RIF related code with router codeIdo Schimmel2017-03-103-642/+644
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The inetaddr notification block is currently implemented in the main driver file, but this isn't really appropriate, as it mainly creates and destroys router interfaces (RIFs) which belong with the rest of the router code. This will become even more apparent later on when we'll need to bind these RIFs to virtual routers according to the VRF's table. Structure the driver better and prevent unnecessary function exports by moving the RIF related code with the rest of the router code.
