I was trying the pfcount_multichannel on a broadcom netxtreme II 5709 card.
The pfcount_multichannel identified 8 rx queues, kernel dmesg recognized
8 rx and 8 tx queues. However, the pfcount_multichannel program only see
packets from queue 0.
Exactly the same test, but with an Intel 82576 card, all 8 channels are
receiving about the same number of packets.
Wonder if there is a bnx2 variable I need to tweak.
