2016-01-22linux-generic: packet_io: separate locks for RX/TXZoltan Kiss
It's possible that two threads want to use the same packet IO in the same time, but one wants RX while the other wants TX. In this case they would block each other unnecessary on the same lock. This could be seen e.g. with odp_l2fwd. Replace that lock with two new ones for each direction. Most callers need both, but send and receive can work with only one.

Restructure odp_init_global() and odp_init_local() so that they recover cleanly if initialization fails. At exit any partial initialization is reversed so that system is in the same state as before the failing call was made. This includes adding dummy termination calls for functions that do not require explicit cleanup for symmetry and future-proofing.

The linux-generic implementation of odp_time_t makes use of POSIX APIs that are sensitive to the _POSIX_C_SOURCE level. Use an indirection mechanism so that these dependencies do not "bleed through" the ODP API. This means that ODP applications can be independent of _POSIX_C_SOURCE level.

2015-12-14linux-generic: pktio: add tap pktio typeIlya Maximets
Creates a new pktio type that allows for creating and sending/receiving packets through TAP interface. It is intended for use as a simple conventional communication method between applications that use kernel network stack (ping, ssh, iperf, etc.) and ODP applications for the purpose of functional testing and can be used as it is with some of the existing example applications. To use this interface the name passed to odp_pktio_open() must begin with "tap:" and be in the format: tap:iface iface the name of TAP device to be created. TUN/TAP kernel module should be loaded to use this pktio. There should be no device named 'iface' in the system. The total length of the 'iface' is limited by IF_NAMESIZE.
