Giuseppe CAVALLARO 45db81e159 stmmac: limit max_mtu in case of 4KiB and use __netdev_alloc_skb (V2) ... Problem using big mtu around 4096 bytes is you end allocating (4096 +NET_SKB_PAD + NET_IP_ALIGN + sizeof(struct skb_shared_info) bytes -> 8192 bytes : order-1 pages It's better to limit the mtu to SKB_MAX_HEAD(NET_SKB_PAD), to have no more than one page per skb. Also the patch changes the netdev_alloc_skb_ip_align() done in init_dma_desc_rings() and uses a variant allowing GFP_KERNEL allocations allowing the driver to load even in case of memory pressure.
