net: libwx: Fix statistics of multicast packets

Jiawen Wu · kuba-moo · commit 06ac0776d549 · 2025-05-27T18:17:11.000-07:00
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.
