strange kernel errors in logs

[nikkon]

Hi all,

I just noticed that I have some strange messages in logs:
Dec 28 13:21:04   kernel: 064.618260 [ 760] generic_netmap_dtor Restored native NA 0
Dec 28 13:21:04   kernel: 064.618236 [ 262] generic_find_num_queues called, in txq 0 rxq 0
Dec 28 13:21:04   kernel: 064.618202 [ 254] generic_find_num_desc called, in tx 1024 rx 1024

Dec 28 13:20:51   kernel: 051.459437 [ 254] generic_find_num_desc called, in tx 1024 rx 1024

Does anyone have any clue?
