[dpdk-dev] [PATCH v1 1/4] net/hinic: the queues resource free problem fixes

[Xiaoyun wang]

Adds tx_queues and rx_queues non-null judgment before free tx or
rx resources, because some app may set tx_queues or rx_queues to
be null before call free resource interfaces, which may cause
a segfault.

Fixes: 64727024d2fd ("net/hinic: add device initialization")
