[dpdk-stable] [PATCH] net/ena: TX L4 offloads should not be set in RX path

[Rafał Kozik]

Hello,

I send this patch to stable list by mistake. I misunderstood git-send
configuration.
Currently this patch is under review on dpdk-dev list
http://dpdk.org/ml/archives/dev/2018-January/089053.html.

I am very sorry about the trouble I caused, I assure you that it will
never happen again.

Kind regards,
Rafal Kozik
