:( I don't know if you saw my reply to it then...

To quote :
"
  I tested that series on socfpga with :

    - 1 instance using RGMII, w/ a ksz9031 PHY, and it works well,
      traffic flows, ethtool seems to report correct data

    - 1 instance that has the Lynx PCS (DMA_HW_FEATURE[30:28] == 0)

  This also works perfectly, switching between SGMII/1000BaseX dynamically
  by hotswapping SFP modules works well, no regression found at a first glance.
"

All the boards I have that have a flavour of stmmac don't seem to have the
internal PCS, are you still interested in some testing , just
for non-regression ?

 This is a subset of RFC v2, but with patches 13 and 14
