Subject: mbuf: remove UDP tunnel flag
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=c9433176b32a34ee2f44f4edce5236e9f13110a1

mbuf: remove UDP tunnel flag

Since previous commit, the flag PKT_TX_UDP_TUNNEL_PKT is not used by any PMD,
remove it from mbuf API and from csumonly (testpmd). In csumonly, the
PKT_TX_OUTER_IP_CKSUM flag is already set for vxlan checksum, providing
enough information to the underlying driver.
