net: stmmac: Fix TSO descriptor with Enhanced Addressing
When using addressing > 32 bits the TSO first descriptor only has the header so we can't set the payload field for this descriptor. Let's reset the variable so that buffer 2 value is zero. Fixes: a993db88d17d ("net: stmmac: Enable support for > 32 Bits addressing in XGMAC") Signed-off-by: Jose Abreu <Jose.Abreu@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>
