net: stmmac: fix dma physical address of descriptor when display ring
stable inclusion from stable-5.10.27 commit 50c75680bdce30df9497a620db9d2c1ea5f8a3a2 bugzilla: 51493 -------------------------------- [ Upstream commit bfaf91ca ] Driver uses dma_alloc_coherent to allocate dma memory for descriptors, dma_alloc_coherent will return both the virtual address and physical address. AFAIK, virt_to_phys could not convert virtual address to physical address, for which memory is allocated by dma_alloc_coherent. dwmac4_display_ring() function is broken for various descriptor, it only support normal descriptor(struct dma_desc) now, this patch also extends to support all descriptor types.
