[PATCH net-next v2] drivers: net: netdevsim: fix devlink_trap selftests failing

From: Oleksandr Mazur
Date: Thu Jun 17 2021 - 07:36:59 EST


devlink_trap tests for the netdevsim fail due to misspelled
debugfs file name. Change this name, as well as name of callback
function, to match the naming as in the devlink itself - 'trap_drop_counter'.

Test-results:
selftests: drivers/net/netdevsim: devlink_trap.sh
TEST: Initialization [ OK ]
TEST: Trap action [ OK ]
TEST: Trap metadata [ OK ]
TEST: Non-existing trap [ OK ]
TEST: Non-existing trap action [ OK ]
TEST: Trap statistics [ OK ]
TEST: Trap group action [ OK ]
TEST: Non-existing trap group [ OK ]
TEST: Trap group statistics [ OK ]
TEST: Trap policer [ OK ]
TEST: Trap policer binding [ OK ]
TEST: Port delete [ OK ]
TEST: Device delete [ OK ]

V2:
1) change the name of the debugfs-entry variable inside nsim_dev to match the name of
the entry itself.
2) change name of the registered devlink callback-ops function to match the
'trap_drop_counter' naming convention.
