Ingress padding boundary values got changed for T6.
    T5: 0=32B 1=64B 2=128B 3=256B 4=512B 5=1024B 6=2048B 7=4096B
    T6: 0=8B  1=16B 2=32B  3=64B  4=128B 5=128B  6=256B  7=512B

Updating the driver to set the correct boundary values in SGE_CONTROL to
32B.
Also, need to take care of this fl alignment change when calculating the
next packet offset.
