Subject: net/null: fix multi-process Rx and Tx
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=bccc77a6a74a6c30e68f88b2ef0d0099c45898c8;p=dpdk.git

net/null: fix multi-process Rx and Tx

Packet processing in secondary process cannot work because rx_pkt_burst
and tx_pkt_burst in eth_dev are not initialized while probing device.
This patch is to the initialization.

Fixes: ee27edbe0c10 ("drivers/net: share vdev data to secondary process")
