Subject: app/testpmd: add items eth/vlan to flow command
X-Git-Tag: spdx-start~5245
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=6df81b325fa4;p=dpdk.git

app/testpmd: add items eth/vlan to flow command

These pattern items match basic Ethernet headers (source, destination and
type) and related 802.1Q/ad VLAN headers.
