The function always check if 'n' is not NULL before calling pg_brick_dot_add. So, I've move the check of 'n' in pg_brick_dot_add which enable code removal. Signed-off-by: Matthias Gatto <matthias.gatto@outscale.com>
1: use &~ instead or ^ to unset mac, because if we xor on an alerady unser mac xor will set other variables 2: add a comment about how an UB can be ignored 3: use vilatile for 2 variables in mac-table-it-next.h: there is this loop: for (;i < PG_MAC_TABLE_MASK_SIZE ; m0 = ma->mask[i]) it seems gcc find it smart to unroll it, and not checking properly the condition. (may be an UB somewhere, hope not) doing so, without volatile it seems i can be > to PG_MAC_TABLE_MASK_SIZE which lead to overflow. 4: move ++i out of the loop, because otherwise it can access an space which is undefined Signed-off-by: Matthias Gatto <matthias.gatto@outscale.com>

The flag -g is for debugging purpose right? Maybe we should remove it... (I don't now about the -02...)

maybe,
I've use that as default flag because that the default flag on autotool
also, I like debug symbols by default, size doesn't matter that much, debug-ability does
it's the default with autotool, and a better default that no optimisaion nor debug symboles. Signed-off-by: Matthias Gatto <matthias.gatto@outscale.com>
Until recently packetgraph version was hardcoded in the Makefile,
and we had no way to ghet the version in C.
It's now resolve by adding 4 define in "common.h"
those defines are:
PG_VERSION_YEAR: year of last DPDK release on which packetgraph is bases
PG_VERSION_MONTH: month of DPDK release
PG_VERSION_REVISION: number of revisions on the release
PG_VERSION: number containing all information above
As we need to got thoses informations for the linker in the makefile,
we are compiling an intermediate program in the configure that ghenerate a
version.mk which is then use in the makefile.
So we are now generating a libpacketgraph.so.19.2.0 instead of
libpacketgraph.so.17.5.0.
