The memory type of the resulting xdp_frame\ndepends on the memory type of the xdp_buff. For page pool based xdp_buff\nit produces xdp_frame with memory type MEM_TYPE_PAGE_POOL. For zero copy\nXSK pool based xdp_buff it produces xdp_frame with memory type\nMEM_TYPE_PAGE_ORDER0. However, stmmac_xdp_xmit_back() does not check the\nmemory type and always uses the page pool type, this leads to invalid\nmappings and causes the crash. Therefore, check the xdp_buff memory type\nin stmmac_xdp_xmit_back() to fix this issue.",
