Re: [dpdk-dev] [PATCH] raw/ifpga: modify log output.

["Xu, Rosen" <rosen.xu@intel.com>]

Hi,

This macro IFPGA_RAWDEV_PMD_FUNC_TRACE is very useful for developer.
To enable this macro, pls follow these guides:
1. enable gcc debug mode such as options: EXTRA_CFLAGS='-O0 -g'
2. add this option in testpmd startup: --log-level=driver.raw.init,8
