Suppressing it means clearing the enable and bypass-timer bits in register 0x14, then resetting the PHY. Patch 4 marks QCA8337 internal CPU PHYs for this treatment; patch 5 performs the register update before reset. The v2 commit message claimed that waiting for the conduit PHY caused the loss of Gigabit advertisement. I have not established that cause, so v3 removes the claim. Thanks, Yongzhao Chen
