* | net: skb_shared_info optimizationEric Dumazet2009-06-081-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | skb_dma_unmap() is quite expensive for small packets, because we use two different cache lines from skb_shared_info. One to access nr_frags, one to access dma_maps[0] Instead of dma_maps being an array of MAX_SKB_FRAGS + 1 elements, let dma_head alone in a new dma_head field, close to nr_frags, to reduce cache lines misses. Tested on my dev machine (bnx2 & tg3 adapters), nice speedup ! Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | net: dont update dev->trans_startEric Dumazet2009-05-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Second round of drivers for Gb cards (and NIU one I forgot in the 10GB round) Now that core network takes care of trans_start updates, dont do it in drivers themselves, if possible. Drivers can avoid one cache miss (on dev->trans_start) in their start_xmit() handler. Exceptions are NETIF_F_LLTX drivers Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* | igbvf: cleanup flags and allow for rx checksum to be disabledAlexander Duyck2009-05-063-33/+26
|/ | | | | | | | | | This patch cleans up a number of unused or unneeded feature flags. As a result of these changes the user should now be able to enable or disable rx checksumming via ethtool.

* igbvf: fix unused external referencesAlexander Duyck2009-04-114-8/+7
| | | | | | | | | | | The igbvbf driver exposed several unused extrnal references due to the fact that code was copied from igb and then some functionality was removed. This changes that so that unused functions are either removed or made static.

* igbvf: add new driver to support 82576 virtual functionsAlexander Duyck2009-04-0810-0/+5153
This adds an igbvf driver to handle virtual functions provided by the igb driver when SR-IOV has been enabled. A virtual function is a lightweight pci-e function that supports a single queue and shares resources with the 82576 physical function contained within the igb driver. To spawn virtual functions from the igb driver all that is needed is to enable CONFIG_PCI_IOV and have an 82576 Ethernet adapter on a system that supports SR-IOV in the BIOS. The virtual functions will appear after the interface is loaded.
