https://git.shady.money/linux/atom?h=v5.112020-11-06T19:28:50Znetdevsim: Add devlink resource for nexthops2020-11-06T19:28:50ZIdo Schimmelidosch@nvidia.com2020-11-04T13:30:37Zurn:sha1:35266255d61c777abd69c2faaa44c92b5a0483c2
The Spectrum ASIC has a dedicated table where nexthops (i.e., adjacency
entries) are populated. The size of this table can be controlled via
devlink-resource.
Add such a resource to netdevsim so that its occupancy will reflect the
number of nexthop objects currently programmed to the device.
By limiting the size of the resource, error paths could be exercised and
tested.
Example output:
# devlink resource show netdevsim/netdevsim10
netdevsim/netdevsim10:
name IPv4 size unlimited unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none
resources:
name fib size unlimited occ 4 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none
name fib-rules size unlimited occ 3 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none
name IPv6 size unlimited unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none
resources:

devlink: rename and expand devlink-trap-netdevsim.rst2020-01-11T01:07:00ZJacob Kellerjacob.e.keller@intel.com2020-01-09T22:46:22Zurn:sha1:04e4272cb3ae2bbb7a5d672918092366f48c9f52
Rename the trap-specific netdevimsim.rst file, and expand it to include
documentation of all the devlink features currently implemented by the
netdevsim driver code.
