[dpdk-dev] [Bug] Static constructors considered evil

[Jean Tourrilhes]

	Hi,

	Expecting static constructors to match between the primary and
the secondary is ill advised and putting yourself at the mercy of the
linker magic. In this case, both primary and secondary were compiled
using the same DPDK directory and exact same libdpdk.a.

PANIC in rte_eal_init():
