Subject: net: eth: altera: fix napi poll_list corruption
From: Atsushi Nemoto <[email protected]>
[ 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().
