A system/cpu can be loaded by a hacker with flooding of broadcast or
multicast packets, to prevent this some Ethernet controllers like CPSW
provide a mechanism to limit the broadcast/multicast packet rate via
hardware limiters. This patch series enables this feature via
Ethtool Coalesce.

This is pretty bogus if you ask me.

What is the difference from accepting a high rate of unicast packets?
I say it is no different.

Therefore, this feature makes no sense to me at all.
