SVN rev 185596 on 2008-12-04 01:58:40Z by yongari
Add support for newer JMC250/JMC260 revisions.
o Chip full mask revision 2 or later controllers have to
set correct Tx MAC and Tx offload clock depending on negotiated
link speed.
o JMC260 chip full mask revision 2 has a silicon bug that can't
handle 64bit DMA addressing. Add workaround to the bug by
limiting DMA address space to be within 32bit.
o Valid FIFO space of receive control and status register was
changed on chip full mask revision 2 or later controllers. For
these controllers, use default 16QW as it's supposed to be the
safest value for maximum PCIe compatibility. JMicron confirmed
performance will not be reduced even if the FIFO space is set
to 16QW.
o When interface is put into suspend/shutdown state, remove Tx MAC
and Tx offload clock to save more power. We don't need Tx clock
at all in this state.
o Added new register definition for chip full mask revision 2 or
later controllers.
Thanks to JMicron for their continuous support of FreeBSD.
