Myri10GE 1.3.1 Linux (July 17, 2007)

Myri10GE 1.3.0 Linux (April 12, 2007)
-------------------
ENHANCEMENTS:
1) Added support for building the firmware into the myri10ge
   kernel module.

   treated as multicast packets and filtered when adopting older
   firmware. 
2) Fixed a bug which could negatively impact communications between
   hosts with different MTUs when TSO is enabled.
3) Fixed a bug which could lead to incorrect hardware checksums being
   reported for frames padded with non-zero data when LRO was enabled.
4) Worked around bugs present in kernels older than 2.6.18 which are
   triggered by receiving non-IP traffic into fragmented skbs.
5) Fixed a bug which could result in memory corruption when our device
   was configured with an MTU between 5996 and 8044 bytes on a machine
   using 16KB pages.

Myri10GE 1.2.0 Linux (January 10, 2007)
-------------------

ENHANCEMENTS:
1) LRO is now supported for 802.1q vlan tagged frames.
2) Support for Linux kernel versions up to 2.6.20.
3) Firmware version 1.4.11.

BUG FIXES:
1) Fixed a bug where the watchdog hander could race
   with the interrupt handler.
2) Fixed a bug where frames received via LRO were not reflected
   in our interface statistics counters.
3) Fixed a bug where padded frames were treated improperly by
   the LRO code.
4) Fixed handling of reserved ethernet packets (01:80:c2:00:00:0X)
   which had been silently dropped.  They will now increment the
   dropped_link_error_or_filtered counter unless the device is 
   in promisc mode, in which case they will be passed up to the driver.
5) Workaround PCIE deadlock for some PM transitions sequence.
6) Firmware ensures -0 is never used in the ipv4 header checksum field 
   (TSO case). Known receivers don't distinguish between +0 and -0, but
   RFC1624 recommends to be safe.


Myri10GE 1.1.0 Linux (September 8, 2006)
-------------------

BUG FIXES:
1) Fixed a bug where the watchdog reset handler might
   be invoked spuriously.
2) Fixed firmware bug where the firmware could send runt
   frames when TSO is enabled.

ENHANCEMENTS:
1) Multicast filtering support.
2) TCP Large Receive Offload support.  This support is
   presently limited to TCP over IPv4, with no VLANs. It is
   done entirely within the driver.
3) The receive portion of the driver was re-written so as to
   avoid large physically contiguous skb allocations for jumbo
   frames by using multiple pages attached to the skb.
4) Firmware version 1.4.6.

Myri10GE 1.0.0 Linux (June 8, 2006)
-------------------

BUG FIXES:
1) Fixed a bug where ethtool would incorrectly report
   that transmit checksum offload was disabled, when in
   fact it was enabled on older 2.6 kernels.

ENHANCEMENTS:
1) NAPI receive interrupt support is enabled and 
   no longer optional.
2) Many source code cleanups.
3) Modinfo now reports module parameter information.
4) Firmware version 1.4.3.

Myri10GE 0.9.2rc0 Beta (May 31, 2006)
-------------------
BUG FIXES:
1) Firmware fixes a PCI-Express send fifo overrun triggered by
   ethernet interrupt DMAs. This could lead to lockups on Intel E7520
   motherboards when the interrupt coalescing timer is set to 1.

2) Fixed a bug in the Solaris driver which could lead to 
   a null pointer dereference when unplumbing the interface
   under heavy receive load.
3) Fixed a bug in the Solaris driver which could lead to a
   null pointer dereference when the interface  attaches to
   a busy shared interrupt line.

ENHANCEMENTS:
1) Support for MSI interrupts on Solaris.

Myri10GE 0.9.1 Beta (May 25, 2006)
-------------------
BUG FIXES:

1) Firmware fixes a PCI-Express resending bug that shows up on some
   E7520 machines
2) Fixed a bug in the Solaris driver which could lead to 
   a null pointer dereference when plumbing the interface
   if our device is assigned a shared interrupt.

ENHANCEMENTS:
1) Doubled transmit performance on CoolThreads-based UltraSparcs
   by deserializing the Solaris driver's transmit routine.

Myri10GE 0.9.0 Beta (April 15, 2006)
-------------------
BUG FIXES:
1) Fixed a bug where firmware would drop frames when it ran
   out of host buffers to DMA them to even when flow control
   was enabled.

ENHANCEMENTS:
1) Power management support added to firmware and Linux driver.
2) Linux driver will attempt to fall back to using the firmware
   resident in the NIC if hotplug fails to find a firmware image.
3) Linux NAPI support added.
4) Linux driver support for IPv6 checksum offload added.
5) Linux driver now uses a more aggressive watchdog which will catch 
   problems before the kernel's netdev watchdog.
6) Preliminary Linux driver support for parity error recovery added.
7) Firmware version 1.4.0

Myri10GE 0.8.1 Beta (April 6, 2006)
-------------------
BUG FIXES:
1) Fixed a bug where interrupt livelock could prematurely trigger 
   the driver's watchdog timer, causing the nic to be needlessly 
   reset on Linux, Solaris, and MacOSX.
2) Fixed a non-compliance with PCI-Express specification, where the link
   retraining was not being initiated upon REPLAY_NUM Rollover.  This fix
   resolves the hung-network-connections problem observed on Sun T2000
   (Ontario) machines.
3) Fixed two bugs in PCI-Express resending code, which show up when
   it is stressed on Intel 7520 based machine.

ENHANCEMENTS:

1) PCI-Express DMA bandwidth is measured and reported in an OS dependent
   way by the driver.
2) Improved 802.1q VLAN support on Linux.
3) Firmware support for PCI-Express relaxed ordering added to Solaris
   driver.

Myri10GE 0.8.0 Beta (March 29, 2006)
-------------------
BUG FIXES:
1) Linux MSI enablement heuristic sometimes gave incorrect results
   on machines with multiple chipsets.

ENHANCEMENTS:
1) TCP Segmentation Offload (also known as Large Send Offload)
   implemented on Linux and Windows.
2) Interrupt method changed to allow for more events to be 
   processed per interrupt. 
3) MacOSX support added.

Myri10GE 0.7.2 Beta (March 8, 2006)
-------------------
BUG FIXES:
1) Fixed a memory leak which would happen when plumbing
   and unplumbing the Solaris driver.
2) Fixed a potential double free which could happen in
   the error path if plumbing the Solaris driver failed.

ENHANCEMENTS:
1) Improved receive performance on CoolThreads-based UltraSparc 
   systems by optionally doing receive side scaling in the 
   Solaris driver.
2) Improved transmit performance on CoolThreads based UltraSparc 
   systems by optionally doing transmit complete interrupt 
   processing in a different context, and by copying small packets.
3) Firmware bug fixes and optimizations.

Myri10GE 0.7.1 Beta (February 2, 2006)
-------------------

BUG FIXES:
1) Fixed erratic TCP receive performance on Linux caused by the
driver confusing the kernel algorithm which calculates socket buffer
sizes.

Myri10GE 0.7.0 Beta (January 25, 2006)
-------------------
BUG FIXES:
1) Interrupt handler now issues PIO reads when using xPIC interrupts
   to ensure interrupt line is low by the time the handler returns.

   load time on all platforms, and at runtime on Linux.
