[dpdk-dev] [PATCH v2 3/4] common_base: extend RTE_MAX_ETHPORTS from 32 to 1024

[Zhiyong Yang <zhiyong.yang@intel.com>]

The reasons to modify RTE_MAX_ETHPORTS is the following.

1. RTE_MAX_ETHPORTS=32 by default has not met user's requirements
with development of virtualization technology. Some vdev users have
to modify the setting before the compiling.

2. port_id have been extended to 16 bits definition. But for many
samples such as testpmd, l3fwd, num of port is still limited to
RTE_MAX_ETHPORTS=32 by default. This may limit usage of 16 bits
port_id.

So, it is necessary to enlarge RTE_MAX_ETHPORTS to more than 256.
