Subject: [PATCH net-next v2 1/2] net: libwx: Fix statistics of multicast packets

When SR-IOV is enabled, the number of multicast packets is mistakenly
counted starting from queue 0. It would be a wrong count that includes
the packets received on VF. Fix it to count from the correct offset.

Fixes: c52d4b898901 ("net: libwx: Redesign flow when sriov is enabled")
