It aimed to allow power saving depending\non the traffic profile. However, it required a training phase\nand required the user to adjust magic numbers depending on\ntheir workload.\n\nA new and improved mechanism was added in commit id\n682a645438c5, also based on empty polls, implemented a\ncallback mechanism which added 'monitor', 'pause' and 'scale'\nmodes in l3fwd-power. This was and easier mechanism to use,\nso the original empty poll mechanism is no longer needed.\n\nThis patch set removes the experimental empty poll API, the\nempty poll mode from l3fwd-power, and related documentation.\n\nThis is based on a deprecation notice in the previous release.\n\n[1/3] examples/power: remove empty poll mode from\n[2/3] libs/power: remove experimental empty poll API\n[3/3] doc/power: remove empty poll documentation" }
