Subject: app/testpmd: move header generation outside txonly loop
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e54ac3b1d95be4a019af05f3c351d4520a2807f0;p=dpdk.git

app/testpmd: move header generation outside txonly loop

Testpmd txonly copies the src/dst mac address of the port being
processed to ethernet header structure on the stack for every packet.
Move it outside the loop and reuse it.
