Hi Thierry,
Please note that things changed in this patch as a result of:
cff608268baf net: stmmac: dwc-qos: name struct plat_stmmacenet_data consistently
which has now been merged. Are you still happy for me to add your
r-b? The current patch is below.

Subject: [PATCH net-next] net: stmmac: dwc-qos: use generic
stmmac_set_clk_tx_rate()
Use the generic stmmac_set_clk_tx_rate() to configure the MAC transmit
clock.
