Subject: app/testpmd: add option to enable LRO
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4c3ea50880c90a1681c7f4c12a558cff37d01f03;p=dpdk.git

app/testpmd: add option to enable LRO

Introduce a new argument '--enable-lro' to ask testpmd to enable the LRO
feature on enabled ports, like it's done for '--enable-rx-cksum' for
instance.
