| Subject: net: eth: altera: fix napi poll_list corruption |
| |
| From: Atsushi Nemoto <nemoto@toshiba-tops.co.jp> |
| |
| [ Upstream commit 4548a697e4969d695047cebd6d9af5e2f6cc728e ] |
| |
| tse_poll() calls __napi_complete() with irq enabled. This leads napi |
| poll_list corruption and may stop all napi drivers working. |
| Use napi_complete() instead of __napi_complete(). |
