Cited commit mistakenly removed the trap group for externally routed
packets (e.g., via the management interface) and grouped locally routed
and externally routed packet traps under the same group, thereby
subjecting them to the same policer.

This can result in problems, for example, when FRR is restarted and
suddenly all transient traffic is trapped to the CPU because of a
default route through the management interface. Locally routed packets
required to re-establish a BGP connection will never reach the CPU and
the routing tables will not be re-populated.

Fix this by using a different trap group for externally routed packets.

A new file snuck into the tree after all existing documentation
was converted to RST. Convert sja1105's devlink info and move
it where the rest of the drivers are documented.

Add packet traps for packets that are sampled / trapped by ACLs, so that
capable drivers could register them with devlink. Add documentation for
every added packet trap and packet trap group.

This type is used for traps that trap control packets such as ARP
request and IGMP query to the CPU.

Do not report such packets to the kernel's drop monitor as they were not
dropped by the device no encountered an exception during forwarding.

The action is used by control traps such as IGMP query. The packet is
flooded by the device, but also trapped to the CPU in order for the
software bridge to mark the receiving port as a multicast router port.
Such packets are marked with 'skb->offload_fwd_mark = 1' in order to
prevent the software bridge from flooding them again.

Packets that hit exceptions during layer 3 forwarding must be trapped to
the CPU for the control plane to function properly. Create a dedicated
group for them, so that user space could choose to assign a different
policer for them.

The flash memory for the ice hardware contains a block of information
used for link management called the Netlist module.

As this essentially represents another section of firmware, add its
version information to the output of the driver's .info_get handler.

This includes both a version and the first few bytes of a hash of the
module contents.

  fw.netlist -> the version information extracted from the netlist module
  fw.netlist.build-> first 4 bytes of the hash of the contents, similar
                     to fw.mgmt.build
