[dpdk-dev] [PATCH] net/ice: fix integer overflow when computing max_pkt_len

The len variable, used in the computation of max_pkt_len could overflow, if used to store the result of the following computation: ICE_SUPPORT_CHAIN_NUM * rxq->rx_buf_len Since, we could define the mbuf size to have a large value (i.e 13312), and ICE_SUPPORT_CHAIN_NUM is defined as 5, the computa

Greetings, Please review the following patch for the dpdk-next-net-intel branch. The len variable, used in the computation of max_pkt_len could overflow, if used to store the result of the following computation: ICE_SUPPORT_CHAIN_NUM * rxq->rx_buf_len Since, we could define the mbuf size to hav
