- Update the firmware to the latest released firmware
(1.4.3), which corresponds to the firmware in the
latest shipping drivers from Myricom. This firmware
fixes several bugs in the firmware's PCI-e implementation,
and it also changes the driver/firmware interface:
o TSO was added, and changed the format of the transmit
descriptors.
o The firmware no longer counts transmits descriptors,
but frames. So the driver needs to keep a count
of the number of frames sent.
o The weird interrupt strategy changed to a normal receive
return ring. This ring is much bigger, and we may be
able to support DEVICE_POLLING.
o Myricom's header files changed the name of firmware
related #define's and enums (s/_MCP_/FW_).
- Stopped spamming the console with lots of printfs unless
mxge_verbose (or bootverbose) is set.
- Made additional information available via sysctl, including
the results of a PCI-e DMA benchmark run at device reset.
- Decreased the excessively long timeouts when sending commands
from 2 seconds to 20ms.
