From f25f4e44808f0f6c9875d94ef1c41ef86c288eb2 Mon Sep 17 00:00:00 2001 From: Peter P Waskiewicz Jr Date: Fri, 6 Jul 2007 13:36:20 -0700 Subject: [CORE] Stack changes to add multiqueue hardware support API Add the multiqueue hardware device support API to the core network stack. Allow drivers to allocate multiple queues and manage them at the netdev level if they choose to do so. Added a new field to sk_buff, namely queue_mapping, for drivers to know which tx_ring to select based on OS classification of the flow.
