[dpdk-dev] [PATCH 7/8] vmxnet3: get rid of DEBUG ifdefs

[step...@networkplumber.org]

From: Stephen Hemminger <shemm...@brocade.com>

By defining macro as a stub it is possible to get rid of #ifdef's
in the actual code. Always evaluate the argument (even in the stub)
so that there are no extra unused variable errors.
