2019-01-31buffers: reinitialize metadata, add additional validationDamjan Marion1-13/+25
- DPDK overwrites metadata as part of rte_pktmbuf_init(...) so we need reinitialize it - additional checks added to ensure ref_count is never < 1 Change-Id: Ida336f81c4723e8f2e0ad4a70cb7b1ecfff978a0 Signed-off-by: Damjan Marion <damarion@cisco.com>

2018-05-29dpdk: mempool priv intialization must be done before releasing buffers to poolSachin Saxena1-8/+7
- Currently mempool priv size is getting initialized after releasing buffers to pool. This is causing mismatch in expected & real metadata size value and buffers are getting released with wrong offset. (when metadata offset is in use for a given platform) - Since private data size is 0 initially, metadata size don't include space for VLIB_BUFFER_HDR.

2017-10-04dpdk: use vpp physmem allocator for dpdk buffersDamjan Marion1-19/+66
This allows us to have single contignuous allocation for DPDK buffers with single mmap FD, so buffer memory can be easily shared with diffrent process. As a consequence dpdk socket-mem is no longer in charge for allocating buffer memory, but still we need some space allocated for dpdk structures so default socket-mem is reduced form 256 to 64 MB. For a default of 16K buffers per numa node, physmem allocation is now 40MB, so basically this change reduces footprint from 256MB per socket to 48 (64 + 40).
