Subject: app/testpmd: fix crash of tx_first mode with numa
X-Git-Tag: spdx-start~10864
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5886ae07d211e4b5e49806dd183812beb31c67ad;p=dpdk.git

app/testpmd: fix crash of tx_first mode with numa

When NUMA is enabled, the mbuf pool pointer of per-core fwd_lcores structure
is not set, causing a crash when accessing to mbp for txonly burst.

Initialize fwd_lcore after allocating NUMA memory pools.
