dumpcap: weird failure with six IPv6 hosts in the filter

[Isaac Boukris <iboukris@gmail.com>]

Hi Stephen,

For instance, the following filter fais as follows (if I omit one host
it works):
-f "host 1::1 or host 1::1 or host 1::1 or host 1::1 or host 1::1 or host 1::1"

EAL: Error - exiting with code: 1
  Cause: Packet dump enable on 0:0000:13:00.0 failed Connection timed out

On the server side I see:
Jun 16 15:17:08: EAL: failed to send to
(/tmp/dpdk/rte/mp_socket_262131_4a103955de0b7a) due to No such file or
directory
Jun 16 15:17:08: pdump_server(): failed to send to client:No such file
or directory
Jun 16 15:17:08: EAL: Fail to handle message: mp_pdump

Then subsequent requests fail with (even with no filter):
pdump_register_rx_callbacks(): rx callback for port=0 queue=0, already exists

I debugged the dpdk-mp-msg thread with gdb, as far as I can tell it
hangs an awful lot of time on rte_bpf_load() (~15 secs in my env), so
the client times out and by the time the server tries to respond the
client socket doesn't exist anymore.

Thoughts?

Thanks!
