Subject: [PATCH] net-2.6 be2net: fix to get RX IDs 0 and 1

Change made to allocate RX IDs 0 and 1 for the two ports.
To get RX Q IDs 0 and 1 enable RSS Capability for that interface.
RX IDs 0 and 1 have 32 bit drop counters which will take a long time
to wrap around thereby presenting a consistent stats display.
