net: stmmac: xgmac: Disable FPE MMC interrupts

Browse source

[ Upstream commit e54d628a27 ]

Commit aeb18dd076 ("net: stmmac: xgmac: Disable MMC interrupts
by default") tries to disable MMC interrupts to avoid a storm of
unhandled interrupts, but leaves the FPE(Frame Preemption) MMC
interrupts enabled, FPE MMC interrupts can cause the same problem.
Now we mask FPE TX and RX interrupts to disable all MMC interrupts.
