Subject: [PATCH] net/ena: do not set Tx L4 offloads in Rx path

[ upstream commit fd617795679019c7aea5ab1e8c85db02cf53f169 ]

Information about received packet type detected by NIC should be
stored in packet_type field of rte_mbuf. TX L4 offload flags should
not be set in RX path. Only fields that could be set in of_flags
during packet receiving are information if L4 and L3 checksum is
correct.

Fixes: 1173fca25af9 ("ena: add polling-mode driver")
