The status of vega/mxq boards seems a bit confused.
This is the status I have so far:
These designs are not affected by the EEE issue. The patch mentioned
has no effect on these boards.
Some boards run fine at GBit speed (like yours) , some have terrible Tx
throughput (like mine and Martin's one). However, unlike on the
odroidc2, the link is not broken after the test, it is not necessary to
ifdown/ifup the interface to do another test.
I'm wondering if the vega/mxq designs all use the rtl8211f phy ?

Indeed. I won't submit anything for the vega since it has no effect.
