A previous patch (http://dpdk.org/dev/patchwork/patch/12937/) removed some necessary lines about Rx checksum by mistake, this patch adds them back. Fixes: 6046898f5097 ("net/mbuf: remove unused Rx error flags") Signed-off-by: Xiao Wang <redacted> --- drivers/net/fm10k/fm10k_rxtx.c | 10 ++++++++++ 1 file changed, 10 insertions(+)
