We have support for accelerating macvlan devices via the .ndo_dfwd_add_station() netdev op. These accelerated macvlan MAC addresses are stored in the l2_accel structure, separate from the unicast or multicast address lists. If a VLAN is added on top of the macvlan device by the stack, traffic will not properly flow to the macvlan. This occurs because we fail to setup the VLANs for l2_accel MAC addresses. In the non-offloaded case the MAC address is added to the unicast address list, and thus the normal setup for enabling VLANs works as expected. We also need to add VLANs marked from .ndo_vlan_rx_add_vid() into the l2_accel MAC addresses. Otherwise, VLAN traffic will not properly be received by the VLAN devices attached to the offloaded macvlan devices. Fix this by adding necessary logic to setup VLANs not only for the unicast and multicast addresses, but also the l2_accel list. We need similar logic in dfwd_add_station, dfwd_del_station, fm10k_update_vid, and fm10k_restore_rx_state.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
