rx_frm_trunc
Number of frames truncated because an internal FIFO is full.
As a packet is received it is fed by the MAC into a 128K FIFO.
If for any reason the PCI interface cannot keep pace and is
unable to empty the FIFO at a sufficient rate, the MAC will
be unable to feed more of the packet to the FIFO. In this
event the MAC will truncate the frame - marking it as such
and discard the remainder. The driver on seeing a 'partial'
packet which has been truncated will discard it.
