Back with commit c8c240e2 (cfg80211: reg: remove support for built-in regdb, 2015-10-15), support for using CFG80211_INTERNAL_REGDB was removed in favor of loading the regulatory database as firmware file. The documentation of CFG80211_CRDA_SUPPORT was not adjusted, though, which is why it still mentions mentions the old way of loading via the internal regulatory database. Remove it so that the kernel option only mentions using the firmware file. Signed-off-by:

As discussed with Mathy almost two years ago in http://lore.kernel.org/r/20180806224857.14853-1-Mathy.Vanhoef@cs.kuleuven.be we should let userspace process SA-QUERY frames if it wants to, so that it can handle OCV (operating channel validation) which mac80211 doesn't know how to. Evidently I had been expecting Mathy to (re)send such a patch, but he never did, perhaps expecting me to do it after our discussion. In any case, this came up now with OCV getting more attention, so move the code around as discussed there to let userspace handle it, and do it properly. Signed-off-by:

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on.

The device has a trap for IPv6 packets that need be routed and have a unicast link-local destination IP (i.e., fe80::/10). This allows mlxsw to ignore link-local routes, as the packets will be trapped to the CPU in any case. However, since link-local routes are not programmed, it is possible for routed packets to hit the default route which might also be programmed to trap packets. This means that packets with a link-local destination IP might be trapped for the wrong reason. To overcome this, allow programming link-local prefix routes (usually one fe80::/64 per-table), so that the packets will be forwarded until reaching the link-local trap. Signed-off-by:

Bidirectional Forwarding Detection (BFD) provides "low-overhead, short-duration detection of failures in the path between adjacent forwarding engines" (RFC 5880). This is accomplished by exchanging BFD packets between the two forwarding engines. Up until now these packets were trapped via the general local delivery (i.e., IP2ME) trap which also traps a lot of other packets that are not as time-sensitive as BFD packets. Expose dedicated traps for BFD packets so that user space could configure a dedicated policer for them. Signed-off-by:

As explained in commit e6125230 ("mlxsw: spectrum_trap: Introduce dummy group with thin policer"), the purpose of the "thin" policer is to pass as less packets as possible to the CPU. The identifier of this policer is currently set according to the maximum number of used trap groups, but this is fragile: On Spectrum-1 the maximum number of policers is less than the maximum number of trap groups, which might result in an invalid policer identifier in case the number of used trap groups grows beyond the policer limit. Solve this by dynamically allocating the policer identifier. Signed-off-by:

When a packet enters the device it is classified to a filtering identifier (FID) based on the ingress port and VLAN. The FID miss trap is used to trap packets for which a FID could not be found. In mlxsw this trap should only be triggered when a port is enslaved to an OVS bridge and a matching ACL rule could not be found, so as to trigger learning. These packets are therefore completely unrelated to packets hitting local routes and should be in a different group. Move them. Signed-off-by:

The IPv6 Neighbour Discovery (ND) group will be used for various IPv6 packets, not all of which fall under the definition of ND, so rename it to "IPV6" which is more appropriate. Signed-off-by:
