  Modified files:
    sys/dev/bce          if_bce.c if_bcefw.h if_bcereg.h 
  Log:
  - Fixed a problem that would cause kernel panics and "bce0: discard frame .."
    errors (especially when jumbo frames are enabled or in low memory systems)
    because the RX chain was corrupted when an mbuf was mapped to an unexpected
    number of buffers.
  - Fixed a problem that would cause kernel panics when an excessively
    fragmented TX mbuf couldn't be defragmented and was released by
    bce_tx_encap().
