From 02c1602ee7b3e3d062c3eacd374d6a6e3a2ebb73 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sat, 4 Feb 2017 15:25:02 -0800 Subject: net: remove __napi_complete() All __napi_complete() callers have been converted to use the more standard napi_complete_done(), we can now remove this NAPI method for good.
