Subject: r8169: enable napi on resume.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cff4c16296754888b6fd8c886bc860a888e20257;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

r8169: enable napi on resume.

NAPI is disabled during suspend and needs to be enabled on resume. Without
this the driver locks up during resume in rtl_reset_work() trying to disable
NAPI again.
