Someone knows what is happening?To track this bug, I opened the ticket
#543. Please go to the ticket for more details.

Thanks in advance, Matias.

I just replied to your bug but I will reply here as well.

The 4.4 kernel has a bug that is fixed by the following commit:
https://git.kernel.org/cgit/linux/kernel/git/davem/net-next.
git/commit/?id=224516b3a798

I would recommend back-porting it into your kernel and we probably need to
have this queued up for linux-stable as well.

From what I can tell I overlooked adding the following which should have

probably been included in the original patch.
Fixes: a6e544b0a88b ("flow_dissector: Jump to exit code in
__skb_flow_dissect")

Thanks.
