This patch fixes two issues after using iovec iterators: - vlan_offset should be initialized to zero, otherwise unexpected offset will be used in skb_copy_datagram_iter() - advance iovec iterator when vnet_hdr_sz is greater than sizeof(gso), this is the case when mergeable rx buffer were enabled for a virt guest.

With commit d75b1ade ("net: less interrupt masking in NAPI") napi repoll is done only when work_done == budget. bcm_sysport_tx_poll() always returns 0 whether or not we completed the poll quantum. Fix this by returning either 0 when we did complete the TX ring reclaim, or budget to trigger a repoll.

When processing received traffic, pass CHECKSUM_COMPLETE status to the stack, with calculated checksum for non TCP/UDP packets (such as GRE or ICMP). Although the stack expects checksum which doesn't include the pseudo header, the HW adds it. To address that, we are subtracting the pseudo header checksum from the checksum value provided by the HW. In the IPv6 case, we also compute/add the IP header checksum which is not added by the HW for such packets.

On topologies including few levels of PCIe switching X540 can run into an unexpected completion error.
