net: stmmac: xgmac: fix handling of DPP safety error for DMA channels
In the Linux kernel, the following vulnerability has been resolved: net: stmmac: xgmac: fix handling of DPP safety error for DMA channels Commit 56e58d6c8a56 ("net: stmmac: Implement Safety Features in XGMAC core") checks and reports safety errors, but leaves the Data Path Parity Errors for each channel in DMA unhandled at all, lead to a storm of interrupt. Fix it by checking and clearing the DMA_DPP_Interrupt_Status register.
