Oh cool, if you have dma and g_ether working, you should
test it with a variable size ping test loop :) That should
expose any issues within few minutes.

Below is the test script I was using earlier, the
tusb6010 comment there is probably no longer valid.

#!/bin/bash

#
# At least tusb6010 dma needs 32-bit aligned buffers.
# That can be done by setting no_skb_reserve with:
# musb->g.quirk_avoids_skb_reserve = 1;
#

device=$1
size=$2
wraps=0

while [ 1 ]; do
	#echo "Pinging with size $size"
	if ! ping -w0 -c1 -s$size $device > /dev/null 2>&1; then
		break;
	fi
	size=$(expr $size + 1)

	if [ $size -gt 8192 ]; then
		wraps=$(expr $wraps + 1)
		echo "wrapping ($wraps) at $size"
		size=1
	fi
done
echo "Test ran up to $size"
