Is LS1046 SGMII @ QSGMII not support half mode?

[Hmc510]

env:PC ----  (SGMII)LS1046

when I set PC autoneg off,I fond that LS1046 PHY(SGMII) can not link.

PHY(RGMII) is good.

I see that in code: Is LS1046 SGMII @ QSGMII not support half mode?

Hi @Hmc510,

The SGMII protocol doesn't support half duplex.

Please feel free to raise a new ticket for any other new queries.

I have blocked the code here line 343 ~ 347, may I ask if there are any risks. Not considering packet loss

Hi @Hmc510,

I suggest not to block those lines as the half duplex is not support to avoid any unnecessary errors because the half duplex was not thoroughly tested during the SDK implementation.
