[ Upstream commit 34c15202896d11e3974788daf9005a84ec45f7a2 ]
When the address width of DMA is greater than 32, the packet header occupies
a BD descriptor. The starting address of the data should be added to the
header length.
Fixes: a993db88d17d ("net: stmmac: Enable support for > 32 Bits addressing in XGMAC")
