[dpdk-dev] [PATCH] net/ena: update Rx checksum errors on Rx path

[Michal Krawczyk <mk@semihalf.com>]

Rx checksum flags and input errors shouldn't be updated on Tx, as it
would work only for packets forwarding.

The ierrors statistic should be updated on Rx, right after checking
Rx checksum flags if the Rx checksum offload is enabled.
