net: stmmac: mmc_core: Drop interrupt registers from stats The MMC IPC interrupt status and interrupt mask registers are of little use as Ethernet statistics, but incrementing counters based on the current interrupt and interrupt mask registers makes them actively misleading. For example, if the interrupt mask is set to 0x08420842, the current code will increment by that amount each iteration, leading to the following sequence of nonsense: mmc_rx_ipc_intr_mask: 969816526 mmc_rx_ipc_intr_mask: 1108361744 These registers have been included in the Ethernet statistics since the first version of MMC back in 2011 (commit 1c901a46d57). That commit also mentions the MMC interrupts as "something to add later (if actually useful)". If the registers are actually useful, they should probably be part of the Ethernet register dump instead of statistics, but for now, drop the counters for mmc_rx_ipc_intr and mmc_rx_ipc_intr_mask completely.

net: stmmac: xgmac: Disable FPE MMC interrupts Commit aeb18dd07692 ("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.
