BZ #567718 - be2net bug fixes for be3 hardware from Alpha testing

Description:
Before sending a command to the ASIC, version in the request header has to
be set properly. This is necessary for the ARM firmware to send correct
data to the driver.
The be2net is  using the structure for the older generation of the ASIC
and the version should be 0. If it has 1, FW will DMA extended response
information that requires a larger response buffer. This will cause memory
corruption and a system crash could follow.
