I am currently experiencing an issue connecting at 1 Gbps speed on an
embedded
unit that uses the Intel 82574L chipset. ethtool reports that the
1000baseT/Full
is available but whenever I connect it to another system that supports
1000baseT
it connects at only 100 Mbps. One thing I also noticed is that the system
on the
other end (which uses a r8169 driver) reports that the link partner (the
82574L)
is only advertising 10/100 link modes. I am connecting the two systems via
a
CAT 5e crossover cable.
I have also tried compiling the latest out of tree source (e1000e-3.0.4.1)
but I
don't even get a link detected when I connect the two systems. For now I am
trying to focus on debugging the in-tree kernel version.
Here's all the relevant info I can think of:
