Found documentation for this but why is rp_filter=1 bad? That's what
it's currently set to. Ditto for net.ipv4.conf.all.rp_filter. Are you
recommending it because of the dropped packets we're seeing on bond1:
  # ifconfig bond1
  bond1     Link encap:Ethernet  HWaddr 00:1b:21:d3:f6:08  
            inet addr:10.191.58.9  Bcast:10.191.58.255 Mask:255.255.255.0
            inet6 addr: fe80::21b:21ff:fed3:f608/64 Scope:Link
            UP BROADCAST RUNNING MASTER MULTICAST  MTU:9000  Metric:1
            RX packets:9839923 errors:0 dropped:4434 overruns:0 frame:0
            TX packets:15240717 errors:0 dropped:0 overruns:0 carrier:0

We see the same issue with dropped packets on the first bonded
interface, bond0:
  # ifconfig bond0
  bond0     Link encap:Ethernet  HWaddr 00:1b:21:d3:f6:0a  
            UP BROADCAST RUNNING MASTER MULTICAST  MTU:1500  Metric:1
            RX packets:15989558 errors:0 dropped:4436 overruns:0 frame:0
            TX packets:8623601 errors:0 dropped:0 overruns:0 carrier:0
            collisions:0 txqueuelen:0 
            RX bytes:15769948311 (15.7 GB)  TX bytes:2909403062 (2.9 GB)
