r8169: Avoid memcpy() over-reading of ETH_SS_STATS
[ Upstream commit da5ac772cfe2a03058b0accfac03fad60c46c24d ] In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally reading across neighboring array fields. The memcpy() is copying the entire structure, not just the first array. Adjust the source argument so the compiler can do appropriate bounds checking.
