commit 9def3451710f7d81e16eed65d2c8f2810a926dc2
Author: Chris Morgan <chmorgan@gmail.com>
Date:   Sat Aug 27 17:24:43 2011 -0400

    Convert PcapHeader to a struct and convert its creation from an IntPtr to
    unsafe for significant performance improvement.
    
    Add the unsafe flag to the SharpPcap library so we can use unsafe code.
    
    Switch from casting and copying the data instead of allocating an instance and
    marshalling data into it.
    
    Performance test results from Test/Performance in the source tree:
    
    Baseline:
    346,681 packets parsed / sec
    1,032,907 packets captured / sec
    
    After changes:
    407,989 packets parsed / sec
    1,545,507 packets captured / sec
    
    ~18% increase in packet parsing rate
    ~50% increase in packet capture rate
    
    Note that those are synthetic tests that are reading packets from a capture file.
    Real world results are likely to be significant improvements in line capture rates
    and a reduction in dropped packets.
    
    Change from Michael Giagnocavo<mgg@giagnocavo.net>

    Remove OfflinePcapDevice.cs and OfflineCaptureDevice.cs. OfflinePcapDevice has been
    replaced by CaptureFileReaderDevice
    
    Remove the dump methods from PcapDevice. Writing to capture files has been replaced
    with the CaptureFileWriterDevice.
    
    Remove Example 7 and example 8, these have been replaced with the CreatingCaptureFile and
    ReadingCaptureFile examples
    
    Remove the dump methods from ICaptureDevice

    Switch RawCapture.Data from a virtual property to a class field. ~2.5% performance improvement when parsing packets with Packet.Net and ~20% when reading all of the packet data bytes. Profiling work and change suggested by Michael Giagnocavo <mgg@giagnocavo.net>

commit 831853f0eed12b162e7230a7c777d85ad25ff9f1

    Add a new PacketParsing performance benchmark

Date:   Fri Aug 26 22:44:43 2011 -0400

    Rename Performance/PacketParsing.cs to PacketReading.cs to reflect that the test isn't actually parsing packets, just reading packets

commit ea76f63077b71c87086de9e9e583c3baecf51a92
Author: Chris Morgan <chmorgan@gmail.com>
Date:   Fri Aug 26 22:43:16 2011 -0400

    Switch from using OfflineCaptureDevice to using the newer LibPcap.CaptureFileReaderDevice, OfflinePcapDevice is being deprecated

commit aee8576def8ac9b8c91561e82b2500f0986896bc
Author: Chris Morgan <chmorgan@gmail.com>
Date:   Wed Aug 24 19:29:52 2011 -0400

    Add ICaptureDevice.GetNextPacketPointers and PcapDevice.GetNextPacketPointers that
    return the pointers from the calls to pcap_next_ex(). This enables unmanaged code
    to avoid the overhead of marshalling PcapHeader and packet contents to allocated memory.
    
    Method suggested by Michael Giagnocavo<mgg@giagnocavo.net> after his work to improve
    performance while capturing high rates of packets.

    Add missing parameter to ARP.Resolve()

commit bc30eee7bf30fb8849f95f537054c1c3f202a81f
Author: Chris Morgan <chmorgan@gmail.com>
Date:   Sat Aug 13 11:02:04 2011 -0400

    Modify ARP class to take a device instead of a device name. Fixes an issue where device names can be specific to their lists, eg. the WinPcap device list has names that start with rpcap but LibPcapLiveDeviceList does not. Using a WinPcap device name to look up a LibPcapLiveDevice like the ARP class used to do won't work. Switch instead to passing a device in instead. Also modify the class to only look up IPv4 addresses as ARP is IPv4 only, and remove public properties for the DeviceName, MacAddress and LocalIP, these can now be passed into ARP.Resolve() if desired. Modify Example2 to reflect the changes to the ARP class
