David Christensen 990a2aa530 - 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().
