Subject: app/testpmd: enable fast free Tx offload by default
X-Git-Tag: spdx-start~697
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=07e5f7bd65718461e4c63757248b9c7bab08341f;p=dpdk.git

app/testpmd: enable fast free Tx offload by default

Enable the DEV_TX_OFFLOAD_MBUF_FAST_FREE in case the underlying device
supports.

This is to preserve the previous offloads configuration made according
to the PMD defaults.
