Subject: 8139too: use napi_complete_done()
X-Git-Tag: Ubuntu-5.2.0-15.16~7419^2~221^2~11

8139too: use napi_complete_done()

Use napi_complete_done() instead of __napi_complete() to :

1) Get support of gro_flush_timeout if opt-in
2) Not rearm interrupts for busy-polling users.
3) use standard NAPI API.
