Subject: staging: fsl-dpaa2/eth: Refactor interrupt arming in NAPI poll
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e30bd4f8342ff251d110ab62eadf3ea9bf37c20f;p=openwrt%2Fstaging%2Fblogic.git

staging: fsl-dpaa2/eth: Refactor interrupt arming in NAPI poll

Take into consideration the return value of napi_complete_done(),
since there might be an indication that it's not suitable to
enable driver interrupts yet.
