Add a mutex lock to protect est structure parameters so that the
EST parameters can be updated by other threads.
Mainline version of the patch is okay, but I believe we need one more
mutex_unlock in 5.10.
I think you're right. Looks like it's because we don't have 5a5586112b92
("net: stmmac: support FPE link partner hand-shaking procedure") in 5.10
(and I don't think it makes sense to backport it either).
I've squashed your patch into the backport, thanks!
