The ixgbe imissed statstic originally only contained dropped packets counted by
the RXMPC registers. This change includes additional types of packet drops
counted by the QPRDC registers.
Intel support confimed that the packet drops counted by the QPRDC registers do
not double-count drops counted by RXMPC registers:
"RXMPC counts packets that are dropped because there is no room in the internal
packet buffer. QPRDC counts packets that are dropped because they can't be
transferred to system memory. These packets have been stored in the internal
packet buffer, so there should be no overlap with RXMPC."
