Because in this case at least the driver is requesting a specific 
filename down to the minor and micro level and a change in the filename 
requires a change in the driver?

#define FW_VERSION __stringify(FW_VERSION_MAJOR) "."                    \
         __stringify(FW_VERSION_MINOR) "." __stringify(FW_VERSION_MICRO)
#define FW_FNAME "cxgb3/t3fw-" FW_VERSION ".bin"

rather than the driver having logic to make it willing to accept later 
minor/micro changes by being more sophisticated in its specification of 
firmware file.
