Gleb Smirnoff 1be6acb7c0 A big rewrite of receive Jumbo frame handling. Remove the local Jumbo 
cluster allocator, that wasn't MPSAFE. Instead, utilize our new generic
UMA jumbo cluster allocator. Since UMA gives us a 9k piece that is contigous
in virtual memory, but isn't contigous in physical memory we need to handle
a few segments. To deal with this we utilize Tigon chip feature - extended
RX descriptors, that can handle up to four DMA segments for one frame.

Details:

o Remove bge_alloc_jumbo_mem(), bge_free_jumbo_mem(),
  bge_jalloc(), bge_jfree() functions.
o Remove SLIST heads, bge_jumbo_tag, bge_jumbo_map from softc.
o Use extended RX BDs for Jumbo receive producer ring, and
  initialize it appropriately.
o New bge_newbuf_jumbo():
  - Allocate an mbuf with Jumbo cluster with help of m_cljget().
  - Load the cluster for DMA with help of bus_dmamap_load_mbuf_sg().
  - Assert that we got 3 segments in the DMA mapping.
  - Fill in these 3 segments into the extended RX descriptor.
