[ 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.
