Subject: [net-next PATCH 0/6] net: Alloc NAPI page frags from their own pool
Date: Tue, 09 Dec 2014 19:40:35 -0800	[thread overview]
Message-ID: <20141210033902.2114.68658.stgit@ahduyck-vm-fedora20> (raw)

This patch series implements a means of allocating page fragments without
the need for the local_irq_save/restore in __netdev_alloc_frag.  By doing
this I am able to decrease packet processing time by 11ns per packet in my
test environment.

Alexander Duyck (6):
      net: Split netdev_alloc_frag into __alloc_page_frag and add __napi_alloc_frag
      net: Pull out core bits of __netdev_alloc_skb and add __napi_alloc_skb
      ethernet/intel: Use napi_alloc_skb
      cxgb: Use napi_alloc_skb instead of netdev_alloc_skb_ip_align
      ethernet/realtek: use napi_alloc_skb instead of netdev_alloc_skb_ip_align
      ethernet/broadcom: Use napi_alloc_skb instead of netdev_alloc_skb_ip_align
