When sending a packet to a tunnel device, the dev's hard_header_len could be larger than the skb->len in function packet_length(). In the case of ip6gretap/erspan, hard_header_len = LL_MAX_HEADER + t_hlen, which is around 180, and an ARP packet sent to this tunnel has skb->len = 42. This causes the 'unsign int length' to become super large because it is negative value, causing the later ovs_vport_send to drop it due to over-mtu size. The patch fixes it by setting it to 0.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
