Under switchdev mode we insert an eswitch miss rule causing any
unmatched traffic to be sent towards the PF vport. This miss rule can
be optimized if we break it to two, one case is for multicast traffic and
the other for unicast.
Breaking the miss rule into two (unicast and multicast) allows the firmware
to program the hardware in a more efficient way.
Using ConncetX-5 Ex with IXIA and testpmd (which use IB representors):
IXIA -> NIC -> PF -> IB representor -> NIC -> VF:
- Without this optimization: 9.2 MPPS.
- With this optimization: 18 MPPS.
VF -> NIC -> IB representor-> PF -> NIC -> IXIA:
- Without this optimization: 17 MPPS.
- With this optimization: 23.4 MPPS.

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.
