2016-01-25linux-dpdk: packet_io: reuse linux-generic code and enable classificationZoltan Kiss
This patch reuses odp_packet_io.c and pktio/loop.c from linux-generic's codebase, and plugs the DPDK specific pieces from odp_packet_dpdk.c into that framework. In order to do that the following steps were taken: - sync up odp_packet_io_internal.h: this file is nearly the same, except we use only loop and our DPDK specific parts - move DPDK specific functionality to odp_packet_dpdk.c, and use those functions in dpdk_pktio_ops. The old pktio code will be deleted in a separate patch - enable classification in Makefiles and init: linux-generic code refers to that, that's why we can't do this in separate patches Signed-off-by: Zoltan Kiss <zoltan.kiss@linaro.org>
2015-12-21linux-dpdk: remove clang warningsv1.5.0.0_DPDK_2.2.0-rc1Zoltan Kiss
There is a type compatibility issue in recv_pkt_dpdk(), although it doesn't have an effect as both of them are pointers. The rte_mbuf accessor functions are bringing up alignment change warnings, which are false-positives in this case. These fields are defined with their appropriate type in the original structure, so their alignment is guaranteed, but the reason for these functions is to hide that structure.

2015-11-03linux-dpdk: packet_io: implement start and stop for pktiov1.3.0.0_DPDK_2.1.0Zoltan Kiss
The original implementation in 51226cbd 'Port 5176d3 "linux-generic: add pktio_start and pktio_stop"' was only an empty one, this patch use the relevant DPDK functions. Signed-off-by: Zoltan Kiss <zoltan.kiss@linaro.org>
2015-10-20linux-dpdk: packet_io: merge received packet handling loopsZoltan Kiss
These two loops are going through the same set of packets, it's better to have them in one. Also move those two struct members adjacent to help optimization. Signed-off-by: Zoltan Kiss <zoltan.kiss@linaro.org>

2015-09-08linux-dpdk: pktio: use default RX/TX configuration of the PMDsZoltan Kiss
It is more universal. Later on we should introduce a more flexible way for the applications to fine tune it. Signed-off-by: Zoltan Kiss <zoltan.kiss@linaro.org> Reviewed-by: Ciprian Barbu <ciprian.barbu@enea.com>
2015-09-02linux-dpdk: pktio: handle vector PMDsZoltan Kiss
The ixgbe PMD introduced vector operations on the RX path, and the plan is to change the other drivers into this direction as well. Unfortunately that means these new drivers mandate a minimum burst size for receive, otherwise they don't return any packets. As ODP can't impose such a requirement on applications, we have to deal with it during the receive function. Currently ixgbe requires 32 buffers, it is expected to change to 4 later on. The rest of the packets in the burst are dropped, and a debug message is printed. Signed-off-by: Zoltan Kiss <zoltan.kiss@linaro.org>
2015-07-27linux-dpdk: packet_io: scale down descriptor numbers when pool is smallZoltan Kiss
Depending on the PMD the descriptor rings may need a buffer for each descriptor. And a pool is likely to be used for multiple interfaces. Scale down the descriptor numbers when they are more than a quarter of the pool. Signed-off-by: Zoltan Kiss <zoltan.kiss@linaro.org>

2015-04-23pktio: remove send_pkt_dpdk()Zoltan Kiss
Apart from calling rte_eth_tx_burst the only thing it does is to copy the pkt_table[] array into an another one. As far as I can determine DPDK doesn't touch this array of pointers, so it's not necessary to copy it. I've merged the rest of it into odp_pktio_send() Signed-off-by: Zoltan Kiss <zoltan.kiss@linaro.org>
