Patch 1 adds extack arg to reload, port_split and port_unsplit devlink
operations.
Patch 2 adds extack messages for reload operation in netdevsim.
Patch 3 adds extack messages to port split/unsplit in mlxsw driver.
David Ahern (3):
devlink: Add extack to reload and port_{un,}split operations
netdevsim: Add extack error message for devlink reload
mlxsw: Add extack messages for port_{un,}split failures

devlink reset command can fail if a FIB resource limit is set to a value
lower than the current occupancy. Return a proper message indicating the
reason for the failure.
$ devlink resource sh netdevsim/netdevsim0
netdevsim/netdevsim0:
name IPv4 size unlimited unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none
resources:
name fib size unlimited occ 43 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none
name fib-rules size unlimited occ 4 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:
name fib size unlimited occ 54 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
$ devlink resource set netdevsim/netdevsim0 path /IPv4/fib size 40
$ devlink dev reload netdevsim/netdevsim0
Error: netdevsim: New size is less than current occupancy.
