Can you resend this patch specifying the commit subject in parenthesis
like this:

commit 32fcafbcd1c9f6c7013016a22a5369b4acb93577 ("net/phy: micrel:
Disable asymmetric pause for KSZ9021")

since this is a bugfix, it should probably be targeting the 'net' tree,
rather than the 'net-next' tree, though the patch applies to both cleanly.

Other than that:
