New Revision: 328901
URL: https://svnweb.freebsd.org/changeset/base/328901
Log:
[arswitch] disable ARP copy-to-CPU port for AR9340 for now.
I'll have to go double check to see if it does indeed pass ARP frames between
switch ports with this disabled, but it seems required for the CPU port to see
ARP traffic.
I'll dig into this some more.
