net: dlink: fix multicast stats being counted incorrectly
[ Upstream commit 007a5ffadc4fd51739527f1503b7cf048f31c413 ]
`McstFramesRcvdOk` counts the number of received multicast packets, and
it reports the value correctly.
However, reading `McstFramesRcvdOk` clears the register to zero. As a
result, the driver was reporting only the packets since the last read,
instead of the accumulated total.
Fix this by updating the multicast statistics accumulatively instaed of
instantaneously.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
Tested-on: D-Link DGE-550T Rev-A3
