Improve fifo allocator performance
- add option to preallocate fifos in a segment - track active fifos with doubly linked list instead of vector - update udp redirect test code to read fifo pointers from API call instead of digging them up from fifo segment header - input-node based active-open session generator Change-Id: I804b81e99d95f8690d17e12660c6645995e28a9a Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dbarach@cisco.com>
