[dpdk-dev] [PATCH] examples/ip_fragmentation: fix fail to send un-fragmented packets

> With latest changes l3fwd_simple_forward() blindly set
> (PKT_TX_IPV4 | PKT_TX_IP_CKSUM) ol_flags for all IPv4 packets.
> Though for un-fragmented packets we also do have to set l3_len
> to make HW IP cksum offload to work properly.
> That causes HWi/PMD to drop or generate invalid packets.
> Though for un-fragmented packets we don't need to regenerate
> IPv4 cksum, as L3 header is not modified.
> Fix by setting ol_flags only when required.
> Another small fix - don't set IPv4/IPV6 ether type for unknown
> packet types.

Shouldn't it be 2 separate fixes?
