Subject: [RFC V3 PATCH 10/26] net/netpolicy: add three new NET policies

From: Kan Liang <kan.liang@...el.com>

Introduce three NET policies
CPU policy: configure for higher throughput and lower CPU% (power
saving).
BULK policy: configure for highest throughput.
LATENCY policy: configure for lowest latency.
