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

From: mohammad . athari . ismail
Date: Wed Jun 30 2021 - 05:18:51 EST


From: Mohammad Athari Bin Ismail <mohammad.athari.ismail@xxxxxxxxx>

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")
