From 05817057faba9356900ced61e24a22eef6bc4c87 Mon Sep 17 00:00:00 2001 From: Igor Chauskin Date: Mon, 28 Oct 2019 11:23:33 +0100 Subject: [PATCH] net/ena: fix indication of bad L4 Rx checksums Add checking of l4_csum_checked and frag flags before checking the l4_csum_error flag. In case of IP fragment/unchecked L4 csum - add PKT_RX_L4_CKSUM_UNKNOWN flag to the indicated mbuf.
