Don't mention it, it's just a small assistance

v1 does a great job
number of lost packets decreased by 2.5-3 times
except of this, without the patch I have bit error rate about 0.423531 with MTU=1500
and now with this patch BER=0.
resuls of v2 are about the same as results of v1
tomorrow I can test it in more wide range of frame sizes.
tomorrow I can test v2 again, if it needs to be tested again.
