With 802.1ad support the vlan_ingress code started checking for vlan
protocol mismatch which causes the current tag to be inserted and the
bridge vlan protocol & pvid to be set. The vlan tag insertion changes
the skb mac_header and thus the lookup mac dest pointer which was loaded
prior to calling br_allowed_ingress in br_handle_frame_finish is VLAN_HLEN
bytes off now, pointing to the last two bytes of the destination mac and
the first four of the source mac causing lookups to always fail and
broadcasting all such packets to all ports. Same thing happens for locally
originated packets when passing via br_dev_xmit. So load the dest pointer
after the vlan checks and possible skb change.

README
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.
