Does this patch improve things? 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.
