From: Eric Dumazet Date: Sat, 4 Feb 2017 23:24:55 +0000 (-0800) Subject: pcnet32: use napi_complete_done() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5b2ec6f2be512485cb9fde7eb1119279af524c28;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git pcnet32: 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.
