Doing kmalloc in atomic context is always an issue, more so for a list that can grow significantly. Turns out that the driver only uses the duplicated list of multicast mac addresses to keep track of what addresses to delete from h/w before committing the new list from kernel to h/w back again via set_rx_mode, every time this list gets updated by the kernel. Given that the h/w knows how to add and delete mac addresses based on the mac address value alone, __dev_mc_sync should be the much better choice of kernel API for these operations avoiding the considerable overhead of maintaining a duplicated list in the driver.

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.
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.
