[dpdk-dev] [PATCH 1/2] net/bonding: free mempool used in mode6

[xiangxia.m.yue at gmail.com]

From: Tonghao Zhang <xiangxia.m.yue at gmail.com>

When creating bond device with mode6, dpdk will create
mempool for arp packets. If free the bond device and
create it with same name, there will be an error. Because
the mempool is not freed when destroying bond device.

Fixes: 06fe78b9 ("bond: add mode 6")
Fixes: ea0c20ea ("apps: use helper to create mbuf pools")
