Hi,
I'm having various SIGSEGV crashes in odp_l2fwd during a tcp transfer
between 2 interfaces.
Running on Linux x86 32bit (3.11); Clean ODP at 1c6711ed1d (Nov 27).
# odp_l2fwd -i veth0,veth1 -m 1
An example backtrace:
Program received signal SIGSEGV, Segmentation fault.

When running in "basic" receive mode (ODP_PKTIO_DISABLE_SOCKET_MMSG=y
ODP_PKTIO_DISABLE_SOCKET_MMAP=y) no crashes observed.
Is this familiar?
