Okay, another idea that I hope will work. Please drop the "net: stmmac:
qcom-ethqos: enable inband mode for SGMII" patch so we go back to using
outband mode for everything.
Then, disable the call to ethqos_pcs_set_inband() so inband mode
doesn't get enabled for SGMII - as phylink will be telling the PHY to
disable inband mode.
Does that result in functional 100M, 1G and 2.5G speeds?
Thanks.
