-Subject: [PATCH] net: extract napi poll functionality to __napi_poll()
-
-This commit introduces a new function __napi_poll() which does the main
-logic of the existing napi_poll() function, and will be called by other
-functions in later commits.
-This idea and implementation is done by Felix Fietkau <nbd@nbd.name> and
-is proposed as part of the patch to move napi work to work_queue
-context.
-This commit by itself is a code restructure.
