The support for RTL8102 was added 2 days ago. See Francois's git tree
in r8169-fixes branch.

interesting :-)

It seems (according Realtek's r8101 and r8168 drivers) that not only
RTL810x class but also RTL8168 class hardware don't have rx-missed. r8168
doesn't contain anything regarding RxMissed and r8101's RxMissed stuff
is commented out.
