[dpdk-dev] [PATCH] [new]ixgbe:set txep.mbuf to NULL when calling ixgbe_tx_free_bufs

[Lu, Wenzhuo]

Hi  Peng,
There're 2 versions of ixgbe_tx_queue_release_mbufs. One in ixgbe_rxtx.c, the 
other is in ixgbe_rxtx_vec.c.
What you shown is the one in ixgbe_rxtx.c. You can find the one in 
ixgbe_rxtx_vec.c already has the sanity check for reference count.
Thanks.
