From: Marvin Liu <yong....@intel.com> Build fm10k driver in Suse11 SP3 will be failed for unrecognized flag. cc1: error: unrecognized command line option "-Wno-unused-but-set-variable"
This flag is supported from gcc 4.4, so add gcc version check in fm10k. In the same time, make option check more clear in ixgbe driver.
