Re: [PATCH] net: phy: fix autoneg invalid error state of GBSR register.

quoted

It looks like you are using an old tree.

Yes, it is linux-4.19.y, since 4.19.y does not have autoneg_complete flag,，
This patch adds the condition before
reading GBSR register to fix this error state.

So you first need to fix it in net/master, and then backport it to
older kernels.
