Heiner Kallweit a3a57bf07d net: stmmac: work around sporadic tx issue on link-up ... This is a follow-up to the discussion in [0]. It seems to me that at least the IP version used on Amlogic SoC's sometimes has a problem if register MAC_CTRL_REG is written whilst the chip is still processing a previous write. But that's just a guess. Adding a delay between two writes to this register helps, but we can also simply omit the offending second write. This patch uses the second approach and is based on a suggestion from Qi Duan. Benefit of this approach is that we can save few register writes, also on not affected chip versions.
