When I run the make command on dpdk-1.2.3r2, it show me the following, but
it works on dpdk-1.2.3r1:

== Build lib/librte_eal/linuxapp/igb_uio
  LD

make[2]: *** [librte_eal] Error 2
make[1]: *** [lib] Error 2
make: *** [all] Error 2

And I noticed there is a warning from gcc: --param max-inline-insns-single
limit reached
So I changed the file: lib/librte_eal/linuxapp/igb_uio/Makefile from 50 to
100.
MODULE_CFLAGS += -I$(SRCDIR) --param max-inline-insns-single=100
It works.
And the question is: Is there any change on dpdk-1.2.3r2 let the parameter
max-inline-insns-single not big enough, or there is something wrong at my
env.

Thanks & BR
Bo
