2013-06-07 PF_RING 5.6.0

* PF_RING Kernel module
 - Fixed bug that prevented the PF_RING cluster to work properly with specific traffic

* Documentation
 - User's guide translated to russian (courtesy of ridervka@yandex.ru)

* Libzero
 - Fixed bug that caused the DNA bouncer to process the correct packet

* Examples 
 - pfwrite
   - Added support for the microcloud so that for GTP traffic it is possible to dump traffic of specific IMSI phone
   - Added support for mobile networks (2G/3G/LTE) so that we can dump traffic of specific GTP tunnels
 - pfdump: added cluster id support (courtesy of Doug Burks <doug.burks@gmail.com>)

 - New release for PF_RING-aware igb (igb-4.1.2)

* DNA
 - Added support for Silicom 10 Gbit hw timestamping commodity NIC card
 - Added pfring_flush_tx_packets() for flushing queued tx packets
 - Fixes for cutting packets to snaplen, e1000-dna rx

* Libzero
 - pfdnacluster_master support for multiple instances of multiple applications
 - Added dna_cluster_set_thread_name() to name the master rx/tx threads
 - Fix for direct forwarding with the DNA Cluster
 - Changed len to a ptr in DNA Bouncer decision function to allow user change forwarded packet content and lenght

* Examples

 - Added pfwrite to the package
 - Fix for rate control with huge files in pfsend

---------------------------------------
2013-01-09 PF_RING 5.5.2

* PF_RING library
 - New pfring_open() flag PF_RING_DNA_FIXED_RSS_Q_0 to send all traffic to queue 0.
   Other queues can be selected using hw filters (DNA cards with hw filtering only).
 - Added ability to create a stats file under /proc/net/pf_ring/stats so that
   applications can report stats via the /proc filesystem.
  - pfring_set_application_stats() for reporting stats
  - pfring_get_appl_stats_file_name() for getting the exac filename where the app sets the statistics

* DNA drivers
 - Flow Control disabled by default with the ixgbe-dna driver

* Sample apps
 - New pfdump.c sample app
 - Userspace BPF support with DNA in pfcount.c
 - pfcount.c and pfsend.c update to report stats using pfring_set_application_stats()

* Libzero
 - New experimental pfring_register_zerocopy_tx_ring()
 - New pfdnacluster_mt_rss_frwd sample app (packet forwarding using Libzero
 DNA Cluster for rx/balancing and standard DNA with zero-copy on RSS queues for tx)

* Libpcap
 - pcap_get_pfring_id()
 - pcap_set_master_id()
 - pcap_set_master()
 - pcap_set_application_name()
 - pcap_set_watermark()

* BUG fixes
 - Fix for corrupted VLAN tagged packets
 - Fix for wrong packet len with vlan stripping offload

---------------------------------------
2012-11-24 PF_RING 5.5.1

- updated ixgbe driver to release 3.11.33
- Fixed bug that was causing ixgbe driver not to disable interrupts. This was causing
  a high load on the core handling the interrupts for ixgbe-based card
- libzero: various hugepages improvements and bug fixes
- Added ability to specify PF_RING_RX_PACKET_BOUNCE in pfring_open
- Fixed minor memory leak
- Various improvements to support of hardware timestamp on Silicom Intel-based 10 Gbit adapters
- DNA Bouncer: added direction to pfring_dna_bouncer_decision_func callback (useful in bidirectional mode)
- DNA Cluster: added dna_cluster_set_hugepages_mountpoint() to manually select the hugepages mount point when several are available
- Created architecture specific versions of libzero/DNA for exploiting latest generation of CPUs and thus improve performance
- Update PF_RING-aware igb update (4.0.17)
- Added pf_ring calls to pcap apps

---------------------------------------
