> This series contains updates to ixgbe only. > > Tony updates the driver to advertise 2.5Gb and 5.0Gb if the adapter > supports it. > > Stephen Hemminger renames our dcbnl_ops since it is global to > ixgbe_dcbnl_ops to avoid namespace issues. > > Mark updates the driver version based on the recent changes. > > Alex has the remainder of the changes, starting with consolidating > functions that represent logical steps in the receive process so we can > later update them more easily (and align with igb). Modify the receive > path to only synchronize the length of the frame versus the entire buffer. > Provided performance improvements by adding support for > DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING. Also made additional > performance gains by batching the page count updates instead of doing > them one at a time. Adjusted the receive path to use 3k buffers with > 8k backing them in order to support build_skb with jumbo frames. Made > additional driver improvements by using the length of the packet instead > of the DD status to determine if a new descriptor is ready to be > processed, which cuts down on reads. To reduce code duplication, pulled > apart the receive path into separate functions. Added support for > providing a buffer with headroom and tailroom to allow for shared info > for NET_SKB_PAD and NET_IP_ALIGN. > > The following are changes since commit > b973154a2278c6af0b0efefafb222e0189959659: > atm: idt77252, use setup_timer and mod_timer > and are available in the git repository at: > git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 10GbE Pulled, thanks Jeff.
