[dpdk-dev] fm10k issue with frames bigger than 1536

I'm working with fm10k 100G card, fm10k driver is 0.21.7, testpoint using SDK version- 4.3.2.
I have 2 vms, each one attached to 1 VF- binded with dpdk.
One of the VFs receives a frame of size 1514, it encapsulates it with vxlan and sends the new frame (size 1584) to the 2nd VF.
The result is the frame received in the second VF is cut to a size of 1536. (supposed to be 1584- as it is sent)
I've noticed this patch: http://dpdk.org/dev/patchwork/patch/4954/ which is included in my code, but I couldn't solve the problem.
I've tried enabling jumbo frame (although buffer size (1704) is enough to hold 1584 bytes) and increasing the max_rx_pkt_len.
Any advice?
