2016-01-25linux-generic: packet_io: expose pktio_tbl and is_free()Zoltan Kiss
The table and the accessor would be used by ODP-DPDK, when it scans through all the pktio interfaces to flush out TX completed buffers. Signed-off-by: Zoltan Kiss <zoltan.kiss@linaro.org> Reviewed-by: Stuart Haslam <stuart.haslam@linaro.org> Signed-off-by: Maxim Uvarov <maxim.uvarov@linaro.org>
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.

2015-12-29linux-generic: classification: implements odp_cls_cos_pool_set() apiBalasubramanian Manoharan
Adds support for configuring packet pool to a class-of-service. linux-generic packet parser is enhanced to parse a packet directly from a memory location rather than from odp_packet_t. packet receive code is modified to run packet classifier directly from the stream so that the packet can be allocated from the pool specified by the CoS.
