[PATCH] doc: fix wrongly referencing dev->skb_mark

Section "Flooding L2 domain" says, to avoid duplicated flooding, if skb->offload_fwd_mark is matched with dev->skb_mark, the kernel will drop the packet. However, the relevant code in __dev_queue_xmit compares skb->offload_fwd_mark with dev->offload_fwd_mark, not dev->skb_mark. I guess the text is

igb driver can cause cache invalidation of non-owned memory?

Hi DMA mapping scheme introduced in commit cbc8e55f6fda ('igb: Map entire page and sync half instead of mapping and unmapping half pages') back in 2012, and used up to now, can probably cause breakage of unrelated code on archs with non-coherent caches. With this scheme, page used for Rx is
