[dpdk-dev] [PATCH] mk: fix the combined library problems by replacing it with a linker script

[Martinx - ジェームズ]

Hi Christian,

 You can count on me to help testing DPDK for Ubuntu, I have plans for it!

 I have some experience with Debian packaging too... I'm currently
maintaining few Ubuntu PPAs, for fun...    =)

 Also, I have hardware available, with 10G, 40G and 100G NIC cards and
traffic generators.

 I would love to help! Specially when with DPDK on Xen (plans for in
on PVM, HVM, XenServer and Amazon EC2).

 Just a curiosity, I'm the designer/maintainer of "Xen LiveCD v2.0"
and I would like to build a new version of it, that will be based on
Xenial with DPDK.

 Hope to see DPDK compiling with Xen on 32-bit (it is broken now), so
we can enable it on Ubuntu!

Cheers!
Thiago
