Subject: [PATCH net] net: stmmac: Terminate FPE workqueue in suspend

From: Mohammad Athari Bin Ismail <[email protected]>

Add stmmac_fpe_stop_wq() in stmmac_suspend() to terminate FPE workqueue
during suspend. So, in suspend mode, there will be no FPE workqueue
available. Without this fix, new additional FPE workqueue will be created
in every suspend->resume cycle.

Fixes: 5a5586112b92 ("net: stmmac: support FPE link partner hand-shaking procedure")

<formletter>

This is not the correct way to submit patches for inclusion in the
stable kernel tree. Please read:
https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.

I'm sorry. Will follow the correct process. Thank you for the advice.
