[PATCH net-next v2 04/12] net: stmmac: Add Split Header support and enable it in XGMAC cores

Add the support for Split Header feature in the RX path and enable it in XGMAC cores. With Split Header disabled 'perf stat -d' gives: 86870.624945 task-clock (msec) #0.429 CPUs utilized 1073352 context-switches #0.012 M/sec 1 cpu-migrations #0.000
