> Subject: [PATCH v3] net/ixgbe: fix mbuf leak
> 
> A local test found that repeated port start and stop operations during
> the continuous SSE vector bufflist receiving process will cause the mbuf
> resource to run out. The final positioning is when the port is stopped,
> the mbuf of the pkt_first_seg pointer is not released. Resources leak.
> The patch scheme is to judge whether the pointer is empty when the port
> is stopped, and release the corresponding mbuf if it is not empty.
